摘要:The widespread use of mobile devices with wireless communication interfaces has made applications for mobile networks, particularly mobile ad hoc networks (MANETs), increasingly attractive for physical environments with defective or infrastructure-less communication. Routing protocols for MANETs still present limited message delivery, high latency, and large message overhead, after many years of research efforts, which strongly inhibit the applications of MANETs in practice. Mobile ad hoc Networks (MANETs) pose significant shared communication medium constraints such as limited memory, access channels, and bandwidth to the development of effective communication protocols. Furthermore, multi hop message forwarding multiplies the amount of simultaneous transmissions, which increases network congestion, interference and decreases protocol performance. To solve these problems, we are going to enhance a variation of MANET which we called interest centric mobile ad-hoc network or simply RADNET in which every participant node implements in the network layer an Active Prefix (AP) composed of a prefix and an application interest, which the RADNET protocol uses to identify the nodes, to address the messages, probabilistic message forwarding and name search in a distributed way. This research work aims to enhance the performance of RADNET protocol in MANET by using RED routing algorithm. The work of simulation has been completed with the help of network simulator NS-2. This research work proposes early congestion detection and adaptive routing in MANET by enhancing the performance of RADNET protocol using RED routing technique. To evaluate the effectiveness of RADNET for generating lower disturbance in the shared medium of communication, to enable resource savings and to reduce message overheads, the simulated performances of Enhanced RADNET protocol with traditional RADNET protocol and AODV is compared. Parameters taken for this work are packet loss ratio, bandwidth, packet delay, packet delivery ratio and energy consumption on the base of which it is concluded that the system is enhanced
