|Title:||QoS ROUTING FOR PROVISION OF END-TO-END DELAY GUARANTEE IN MANETs|
|Keywords:||ELECTRONICS AND COMPUTER ENGINEERING|
|Abstract:||A Mobile Ad Hoc Networks (MANET) is a collection of mobile nodes that can communicate with each other using multi hop wireless links without utilizing any fixed based-station infrastructure and centralized management. Each mobile node in the network acts as both a host generating flows or being destination of flows and a router forwarding flows directed to other nodes. Future applications of MANETs are expected to be based on all-IP architecture and be capable of carrying multitude real-time multimedia applications such as voice and, video as well as data. It is very necessary for MANETs to have an efficient routing and quality of service (QoS) mechanism to support diverse applications. This thesis proposes a QoS routing for provision of End-to-End Delay Guarantee (QRED). This algorithm selects routes with least traffic and follows alternate route method for route maintenance. It is also beneficial to avoid traffic congestion and frequent link breaks in communication because of the mobility of nodes. The protocol estimates node delay dynamically and by piggy backing delay information destination nodes will monitor healthy ness of the paths and selects better route in advance of congestion. And the protocol is implemented and simulated using Glomosim simulator. Performance comparisons of the proposed QRED protocol against AODV, and QS-AODV is presented and shown that the proposed algorithm performs well|
