This paper describes a Security Enhanced AODV routing protocol for wireless mesh networks (SEAODV). SEAODV employs Blom’s key pre-distribution scheme to compute the pairwise transient key (PTK) through the flooding of enhanced HELLO message and subsequently uses the established PTK to distribute the group transient key (GTK). PTK and GTK are used for authenticating unicast and broadcast routing...

In different this paper we present the performance evaluation study of a simple broadcast data dissemination technique in new emerging Vehicular Ad hoc Networks (VANETs). Differently from the traditional Mobile Ad hoc NETworks (MANETs), VANETs require particular routing protocols, due to the high dynamism of the network topology, and to different traffic and mobility patterns. For safety and em...

k-ary m-way networks are especially suitable for broadcasting because of the shared nature of m-way channels. A flit placed on an m-way channel can be accepted concurrently by adjacent routers and node interfaces during a given clock cycle. This paper discusses two modified Minimum Spanning Tree (MST) broadcast algorithms that are designed to work efficiently in k-ary mway networks. The algorit...

We present two protocols, a distributed reliable broadcast and a distributed reliable multicast; these protocols are resistant to network partitions in asynchronous distributed systems. They are reliable in the sense that the receiver will eventually receive the message even if the receiver was partitioned away at any time. The protocols are aimed either for large scale or smaller networks. We ...

In this paper, we propose an efficient geo-routing aware MAC protocol (GOAL) for underwater acoustic networks. It smoothly integrates self-adaptation based RTS/CTS, geographic cyber carrier sense and implicit ACK to do combined channel reservation and next hop selection. As a result, it possesses the advantages of both geo-routing protocol and reservation based MAC protocol. Specifically, its s...

Unlike traditional wireless routing protocols which use a single fixed path, opportunistic routing explicitly takes advantage of the broadcast nature of wireless communications by using a set of forwarders to opportunistically perform packet forwarding. A key issue in the design of opportunistic routing protocols is the forwarder list selection problem. In this paper we establish a general theo...

We consider wireless mesh networks, and exploit the inherent broadcast nature of wireless by making use of multipath routing. We present an optimization framework that enables us to derive optimal flow control, routing, scheduling, and rate adaptation schemes, where we use network coding to ease the routing problem. We prove optimality and derive a primal-dual algorithm that lays the basis for ...

This paper presents a thorough survey of current work addressing multicast routing protocols with low control overhead in Mobile Ad hoc Networks (MANETs). There are so many different issues and solutions which witness the need of group management in ad hoc wireless networks. The goal of a multicast routing protocol for MANETs is to support the propagation of data from a sender to all the receiv...

Increasing the lifetime of energy constraint Wireless Sensor Network (WSN) is one of most critical and challenging requirement. In this paper, an Energy Efficient Distributed Multi-Parent (EEDMP) heuristic routing algorithm is proposed to maximize the minimum lifetime of WSN and enhance its reliability. In EEDMP, WSN is considered as a broadcast tree routed to the base station where a sensor no...

The Vehicular Adhoc network is the emerging research area which makes a phrase ‘Network on the wheel”. VANET is a collection of communication vehicles to broadcast desired information. In this paper performance of three routing protocols namely Adhoc On Demand Distance Vector Routing (AODV), Destination Sequence Distance Vector (DSDV) and VANET Radio Broadcasting Protocol (VANETRBC) is compared...
