The performance of mobile ad-hoc networks (MANET) is related to the efficiency of the routing protocols in adapting to frequently changing network topology and link status. This paper addresses the issue by comparing the relative performance of three key ad-hoc routing protocols: Destination-sequenced Distance Vector (DSDV), Ad-hoc Ondemand Distance Vector (AODV) and Optimized Link State Routin...

Mobile ad hoc network is a collection of mobile nodes communicating through wireless channels without any existing network infrastructure or centralized administration. Because of the limited transmission range of wireless network interfaces, multiple "hops" may be needed to exchange data across the network. In order to facilitate communication within the network, a routing protocol is used to ...

In recent days Inter-Vehicle communication has fascinated many research communities and automotive industries .With the introduction of inter-vehicle communication it would be possible for vehicles to communicate with each other and thus this functionality will provide intelligent transportation system as well as many assistant services for drivers and passengers. Vehicular ad-hoc network is an...

Cross layer techniques applied to various protocols stacks provide fair information sharing between OSI model layers. The performance gains have been demonstrated for many studied systems within protocols interactions. The example is illustrative of the reliable transport protocols that use retransmissions to achieve that reliability function. The performance gains of the persistent timeout pol...

Wireless Sensor Networks (WSN) is an emerging technology for attraction of researchers with its research challenges and various application domains. It consists of small nodes with sensing, computation, and wireless communications capabilities. The limited energy resource is one of the main challenges facing the security in such networks. An attempt has been made to compare the performance of t...

Mobile Ad hoc Network (MANET) is an autonomous, self-configuring and infrastructure-less system in which various mobile nodes are connected by wireless links. In Mobile Ad Hoc Network (MANET), various routing protocols are there like AODV, DSDV, TORA, DSR etc. Due to the nature of changing topology and infrastructure less in MANETs there are various issues and constraints which affect the perfo...

Routing process in Wireless Multimedia Sensor Networks (WMSNs) has its own challenges to pass multimedia applications from source nodes to a sink. The WMSNs have specific characteristics consisting of multihop network, restricted bandwidth, and limited power resources in the WMSNs. Additionally, multimedia applications require specific Quality of Service (QoS). This paper proposes a routing opt...

Routing in mobile ad hoc network is considered a challenging task due to the unpredictable changes in the network topology, resulting from the random and frequent movement of the nodes and due to the absence of any centralized control. Several routing protocols for mobile ad-hoc networks are being proposed. In this paper the performance of two major routing protocols for mobile ad hoc networks:...

Security has become one of the major issues for data communication over wired and wireless networks. The dynamic routing algorithm is used to randomize delivery paths for data transmission which is compatible with popular routing protocols, such as the Routing Information Protocol in wired networks and Destination-Sequenced Distance Vector protocol in wireless networks, without introducing extr...
