Process parameter estimation, to a large extent, determines the quality of the industrial production. Traditionally, limited sensors are deployed in production field by elaborate wiring, which cannot provide the accurate estimate in the hostile industrial environment. Recently, industrial wireless sensor network (IWSN) has been considered as one promising technology to improve the process parameter estimation by deploying more sensors flexibly and making them work collaboratively. In this paper, a sequential IWSN (Seq-IWSN) approach is provided for the temperature estimation of the steel slab during the hot strip milling process. In Seq-IWSN, the network deployment and scheduling strategies coupling with the process parameter estimation algorithm are involved.

Mobility of users and enhancement of bandwidth have been characterizing factors for the global telecommunication development which also witnessed improvements in services. If user needs to send some information over the prescribed bandwidth with dure reliability then the (QOS) Quality of services becomes more critical and seeks expected performance. A Mobile Adhoc Network is self-possessed combination of mobile nodes. It has to be self-structured. These are mobility extensions into wireless domain and autonomous mobile dominion. In this set of specified nodes which form adhoc network with routing infrastructure too. Multicasting is responsible for transferring information efficiently from a source to any destination; duplication of messages and delivery takes place only once and that too at the branch points, due to splitting of the destination links. The authors have successfully been able to address several issues relating to MANET, especially multicasting, its routing protocols and qualitative comparisons. Further, in this paper, we particularly focused on implementation as well as performance analysis of multicast routing protocols like AODV, MAODV using network simulator NS3.By using the performance parameter such as average end-to-end delay and packet delivery ratio (PDR) and routing-overhead.

Due to a solid multicast, a procedure can multicast a solitary message to a gathering of procedures interestingly that guarantees that all gathering individuals in the host goal amass can get the same message regardless of whether a portion of the individuals are suspiciously flawed. Multiparty cryptographic conventions and secure circulated administrations are frequently fabricated utilizing multicasts.

We introduce a new, simple, yet effective scheme for reducing the impact of receiver buffer blocking in Multipath TCP (MPTCP). This blocking primarily occurs when the paths have different characteristics. his phenomenon is due to the limited size of the MPTCP receiver buffer. In a nutshell, our scheme allows, under certain conditions, the retransmission of a segment by a different interface than the one used originally and the closure of the badly behaving TCP connection. Our scheme anticipates the problem by opening multiple TCP connections for each interface, but only uses one at a given time. It detects when a segment needs to be retransmitted from another interface,closes the ongoing connection on the original interface, and starts using one of the backup connections.

The present age of sensor systems are intended to be application-particular, hence are presented just to a constrained set of clients. The developing idea of IoT is relied upon to house numerous applications with assorted defer prerequisites. A transmission director gives an ideal transmission time to transmitting the cushioned estimations. In the writing, arrangements have been proposed improving mostly for single detecting foundations. In this work, we initially propose an ideal transmission administrator that backings numerous applications in a solitary jump remote sensor systems. At that point, we expand our arrangement into a dispersed transmission director to work in multi-bounce WSNs. Both transmission supervisors work couple, also, decide the transmission time for each supported estimation. We execute the two arrangements in ns3 and think about with other best in class arrangements. Our contextual analyses demonstrate that our proposed arrangement diminishes vitality utilization by 75% contrasted with the best in class approaches while having all things considered 12% less lapsed estimations.

In Mobile Ad hoc Networks (MANETs), with Optimized Link State Routing Protocol (OLSR) the mobility concept is an essential element which can result in the evolution of network performances. In this paper, the main objective is to develop an algorithm to improve the MultiPoint Relay (MPR) selection process in such networks. This algorithm is based on the Mobility Rate (MR) which in turn is relied on the relative velocity of nodes. Additionally, in this algorithm, each node keeps a mobility rate record of other nodes. Moreover, this mobility value will be exchanged between nodes using OLSR

messages (HELLO and Topology control (TC)). Furthermore, this value will be used as a criterion when a node chooses their MPR set. In addition, the simulation results using Network Simulator 3 (NS3) have shown that the mobility concept could improve network performances in terms of the throughput,

packet received, packet loss, packet delivery ratio and packet forwarded. Moreover, and through this paper the proposed algorithm can be used as a functional mobility mechanism to improve network performances in MANETs.

In multi-radio wireless mesh networks, one node is eligible to transmit packets over multiple channels to different destination nodes simultaneously. This feature of multi-radio wireless mesh network makes high throughput for the network and increase the chance for multi path routing. This is because the multiple channel availability for transmission decreases the probability of the most elegant problem called as interference problem which is either of interflow and intraflow type. For avoiding the problem like interference and maintaining the constant network performance or increasing the performance the WMN need to consider the packet aggregation and packet forwarding. Packet aggregation is process of collecting several packets ready for transmission and sending them to the intended recipient through the channel, while the packet forwarding holds the hop-by-hop routing. But choosing the correct path among different available multiple paths is most the important factor in the both case for a routing algorithm. Hence the most challenging factor is to determine a forwarding strategy which will provide the schedule for each node for transmission within the channel. In this research work we have tried to implement two forwarding strategies for the multi path multi radio WMN as the approximate solution for the above said problem. We have implemented Global State Routing (GSR) which will consider the packet forwarding concept and Aggregation Aware Layer 2 Routing (AAL2R) which considers the both concept i.e. both packet forwarding and packet aggregation. After the successful implementation the network performance has been measured by means of simulation study

Today’s mobile devices almost exclusively connect to infrastructures for communications and information access; but advances such as AirDrop andWiFi Direct are bringing deviceto-device communication to the forefront of mobile computing. Self-organizing ad hoc mobile networks have a wide range of applications in scenarios where infrastructure is not available or with limited bandwidth, such as communications in the aftermath of natural disasters, censorship resistant communications, and battlefield communications. In this paper, we propose an information-centric device-to-device network, called ICD2D. The network is distributed and requires no centralized coordination. For each published item of data, the system creates a metatdata; a publish-subscribe mechanism disseminates the metadata and facilitates filtering information in a distributed fashion. We implemented a full-featured system on NS3. Evaluations show significant improvement in successful information retrieval compared with OLSR (Optimized Link State Routing), a common approach to ad hoc routing.
