Abstrucf-We introduce WRP-Lite, which is a tabledriven routing protocol that use^ non-optimal routes, and compare its performance with the performance of the dynamic source routing (DSR) pmtocol, which is an ondemand routing protocol for wireless ad-hoc networks. We evaluate the performance of WRP-Lite and DSR for varying degree of mobility and traffic In a 20-node network. The performance parameters are end-tolad delay, contml overhead, pententage of packets delivered, and hop distribution. We show that WRP-Lite has much better delay and hop performance while having comparable overhead to DSR
ABSTRAC TWe present source tracing as a new viable approach to routing in ad hoc networks in which routers communicate th e second-to-last hop and distance in preferred paths to destinations . We introduce a table-driven protocol (BEST) i n which routers maintain routing information for all destinations, and an on-demand routing protocol (DST) in whic h routers maintain routing information for only those destinations to whom they need to forward data . Simulatio n experiments are used to compare these protocols with DSR , which has been shown to incur less control overhead tha t other on-demand routing protocols . The simulations show that DST requires far less control packets to achieve comparable or better average delays and percentage of packe t delivered than DSR, and that BEST achieves comparabl e results to DSR while maintaining routing information fo r all destinations .
