Energy level performances of three packet delivery schemes in Wireless Sensor Networks (WSN) are evaluated in presence of Rayleigh fading. Three different information delivery mechanisms are investigated using regenerative relays with or without error correction capability. Energy consumption for successful delivery of a data packet for each mechanism is evaluated and compared under several con...

A wireless Ad-hoc network consists of wireless nodes communicating without the need for a centralized administration, in which all nodes potentially contribute to the routing process. In this paper, we analyze packet scheduling algorithm to find those that most improve performance in congested network. Hence, a scheduling algorithm to schedule the packet based on their priorities will improve t...

Many emerging commercial and military applications require secure multicast communication in adhoc environments. Secure multicast communication in mobile adhoc networks is challenging due to its inherent characteristics of infrastructure-less architecture with lack of central authority, high packet loss rates and limited resources such as bandwidth, time and power. Hence key management is the f...

The majority of the existing ad hoc wireless network routing protocols has a tendency to use the shortest single path from the source to the destination. However, in constantly changing topologies such as those in mobile ad hoc networks, the shortest single path is quite unstable for reachability and also for traffic load equilibrium. In this paper, we propose a novel scheme, called Applicative...

The tremendous growth in automobile industry is increasing the demand for car safety and the car to car connectivity. Vanets which is a super class of Manet are new promising and challenging technology that makes an improvisation in traffic safety and efficiency. It creates a path for intelligent transportation system (ITS).The information that is carried by the vehicles can enrol safety measur...

Vehicular Ad hoc Networks (VANETs) are a specific class of Mobile Ad hoc Networks (MANETs). Since vehicles tend to move in a high speed, the network topology is rapidly changed. Thus vehicle’s connectivity problem is one of the interesting issues in VANETs. Ad hoc On-demand Multipath Distance Vector (AOMDV) is an extended version of ad hoc on-demand distance vector (AODV). AOMDV is designed to ...

In this paper, the Zone Routing Protocol (ZRP) is surveyed for the nature of its parametric performance under various mobility conditions. ZRP is well known as hybrid routing protocol works on various routing phenomenon like Intra-Zone Routing Protocol (IARP) which routes within its routing zone, Inter-Zone Routing Protocol (IERP) which routes outside the routing zone, Bordercast Resolution Pro...

Mobile Ad-hoc Network (MANET) is a self-configuring wireless network of movable and independent nodes which operate without the support of any permanent infrastructure, hence MANET has dynamic topology. In MANET, each node forwards traffic unrelated to its own use. Despite the proliferation of MANET, it is prone to various attacks which include blackhole attack, grayhole attack, flooding attack...
