Many Wireless Sensor Network (WSN) applications necessitate secure multicast services for the purpose of broadcasting delay sensitive data like video files and live telecast at fixed timeslot. This work provides a novel method to deal with end-to-end delay and drop rate of packets. Opportunistic Routing chooses a link based on the maximum probability of packet delivery ratio. Null Key Generatio...

Mobile Ad hoc Networks (MANET’s) have become increasingly popular in infrastructure-less mobile wireless communication system. Nodes of these kinds of networks function as a router which discovers and maintains the route to the other nodes in the networks. Route discovery and packet forwarding operations need an efficient routing protocol. Ad-Hoc on Demand Distance Vector Routing Protocol (AODV...

Security is a major problem in the shared wireless medium of mobile ad hoc networks since it gives a way to the adversaries to launch various devastating attacks on the target network. To reduce this passive eavesdropping we propose an efficient approach for providing security for data and network. Initially, anonymity protection is provided to source, route and destination. Due to this the att...

In recent years, Wireless Sensor Networks (closely deployed nodes) are widely used in applications ranging from weather forecasting to defense. It comprises of data gathering nodes (source), transmitting nodes (routers) and data collecting node. Wide research sprang in this area for improving the efficiency of these networks in terms of packet delivery ratio, throughput and reliability by modif...

We present a greedy data transportation scheme with hard packet deadlines in ad hoc sensor networks of stationary nodes and multiple mobile nodes with scheduled trajectory path and arrival time. In the proposed routing strategy, each stationary ad hoc node en route decides whether to relay a shortest-path stationary node toward destination or a passing-by mobile node that will carry closer to d...

In this paper, we proposed a cluster based routing protocol for mobile ad hoc network. It uses clustering's structure to decrease average end-to-end delay and improve the average packet delivery ratio. We simulate our routing protocol for nodes running the IEEE802.11 MAC. Results of our experiments show that the packet delivery ratio increases greatly and packet delay decreases significantly. I...

Mobile Ad hoc Networks (MANET) use anonymous routing protocols that hide node identities and routes from outside observers in order to provide anonymity protection. Existing anonymous routing protocols relay on hop by hop encryption or redundant traffic by generation high cost. The high cost exacerbates the inherent resource constraint problem in MANETs. Existing anonymous routing protocols pro...

The Objective Function (OF) can be used by the Routing protocol for low power lossy networks (RPL) to construct a Destination Oriented Directed Acyclic Graph (DODAG) based on routing metrics. standard OFs suffer from long hops when selecting route, which may cause consume node's energy faster. In this paper, we suggest an improvement of RPL OF that considers three results show proposed increase...
