Proactive and reactive protocols of MANET are used to route the information over the links to the destination nodes, end-toend and hop-to-hop. In multi-hop mobile ad hoc networks the consumption of energy at the mobile nodes end and its proper utilization is quite necessary. The nodes and other routing resources in the MANETs do not afford to waste battery power during the critical operations l...

Wireless sensor networks are composed of a large number of sensors and their major challenge is energy consumption in order to prolong the life time of the network. From the security point of view, detecting schemes must be very light to increase the life time of the network. In this paper, defensive mechanisms based on cumulative acknowledgement and energy based is proposed to detect selective...

On-demand routing protocols for Mobile Ad-hoc networks registers unexpected performance behavior when multiple data streams are sent to common destination. This scenario is common when MANET is connected to Internet through common gateways or used in similar cases. The AODV outperform DSR in the normal situation but in the constrained situation DSR out-performs AODV, the degradation is as sever...

Current multipath protocols for Multi-Hop Wireless Networks (MWNs) use hop-count as the default route selection criteria. Route selection should also consider network and link conditions. We propose a networkenvironment-aware trust-based route selection framework for MWNs that makes informed and adaptive route-selection decisions. A node quantifies trust values for its neighboring nodes and for...

Ad hoc networks are characterized by multi hop wireless connectivity, frequently changing network topology and the need for efficient dynamic routing protocols. This report compares the performance of MANET routing protocol such as Ad-hoc On Demand Distance Vector (AODV), LocationAided Routing (LAR1) and Wireless Routing Protocol (WRP) protocol at different Simulation time using a parallel disc...

This paper presents a Dynamic Source Routing Protocol using Self Healing and Optimizing Routing Technique based on fuzzy logic concepts. The paths generated by conventional dynamical source routing protocol deviate far from the optimal paths because of the lack of knowledge about the global topology and the mobility of nodes. Routing optimality affects the network performance, especially when t...

Mobile Adhoc Network (MANET) is a collection of wireless mobile nodes that dynamically form a network temporarily without any support of central administration. Moreover, every node in MANET moves arbitrarily making the multi-hop network topology to change randomly at unpredictable times. There are several familiar routing protocols like DSDV, AODV, ZRP, etc... which have been proposed for prov...

A Mobile Ad-Hoc Network (MANET) is a collection of wireless mobile nodes that communicates with each other without using any existing infrastructure, access point or centralized administration. In this paper, an attempt has been made to evaluate the performance of three well known routing protocols AODV, DSR and WRP with two traffic Generators CBR and FTP by using two performance metrics such a...

Route discovery in many mobile ad hoc protocols is based on flooding. However, flooding suffers from high overhead, which can increase contention and communication delays. In this paper, we propose two new route discovery algorithms that are aimed towards reducing these delays. Both algorithms are suitable for use with ad hoc protocols where nodes periodically broadcast Hello Messages. Using th...

This document describes the architectural design of the simulation environment for the BISON project. Given the different simulation requirements (in terms of scalability, network models, level of detail) needed by ad-hoc networks and overlay networks, we propose two different architectures. The simulation architecture for ad-hoc networks builds up on an existing packet-level simulator, namely ...
