One of the major challenges faced by the Ad hoc networks is battery life of the nodes. By reducing or optimizing the energy consumed during the communication, the life of the respective nodes can be increased thereby improving the network lifetime. However the energy consumed in communication is greatly affected by the quality of link between the nodes. In this paper, we propose RSSI based Opti...

Vehicular Ad Hoc Network (VANET) is a part of Mobile Ad Hoc Networks (MANET). Wireless communication among vehicles and static road side infrastructure is provided by VANET. The communication among vehicles is important for comfort, safety and for entertainment purpose as well. The communication performance depends on the routing protocols that are being employed in network. In this paper, we h...

We present m-limited forwarding, a technique to reduce the cost of disseminating information in a power-constrained environment by limiting the cardinality of the subset of nodes which retransmit a packet. We show how this technique can be used to improve the performance of ad hoc routing protocols. m-AODV applies m-limited forwarding to the AODV routing protocol, and is used for networks with ...

Intrusion detection and secure routing schemes have been proposed for increasing the security and reliability in critical scenarios like mobile ad hoc networks. In this paper we present an integrated secure routing system based on Intrusion Detection Systems (IDS) and SUCV (Statistically Unique and Cryptographically Verifiable) identifiers. The proposed IDS has been used for the support of secu...

A mobile ad hoc network (MANET) is a collection of mobile nodes where each node is free to move about arbitrarily. The Ad Hoc On-Demand Distance Vector AODV) routing protocol is one of the well-known and efficient on-demand MANET protocols. AODV currently does not support Quality of Service (QoS) and also has no load balancing mechanism. We propose some enhancements to the AODV protocol to prov...

Recent advances in wireless networks have prompted much research attention in the area of wireless sensor network (WSN). Sensor network consists of hundreds to thousands of low power multifunctioning sensor nodes operating in hostile environment with limited computational and sensing capabilities. These sensor devices are susceptible to various attacks such as selective forwarding or sinkhole a...

The Ad hoc On-demand Distance-Vector routing protocol (AODV) was published in 2003 by the IETF, as experimental RFC 3561. This routing protocol was one of four routing protocols, developed by the IETF for use in mobile ad hoc networks (MANETs) – with the other being DSR, TBRPF and OLSR. As operational experiences with these protocols accumulated, the IETF set forth on standardization of OLSRv2,...

A mobile ad hoc network is networks which utilizes multi-hop radio relaying and are capable of operating without the support of any fixed infrastructure. Efficient dynamic routing is a challenge in such a network. On-demand routing protocol is widely developed in ad hoc networks because of its effectiveness and efficiency. In this paper, the significance of Ad hoc On-Demand Distance Vector (AOD...
