Abstract

This paper presents the MSBR protocol. MSBR is a Quality of Service (QoS) reactive protocol which uses a new metric to choose reliable and stable multiple routes among those found during the discovery phase. To determine the best selection of routes among those returned, MSBR uses a new metric, the "combined reliability based on trust" to determine the most reliable paths among those found. A single path version of MSBR, called SBR, can also be used to find paths with a minimum required end-to-end reliability. The multiple paths chosen by MSBR are used to send data simultaneously on multiple routes. In MSBR, the route reconstruction phase can be partial or complete. Both versions were evaluated. Simulation results show that the new metric describes well the reliability of the discovered routes. They also show that MSBR with complete route reconstruction makes a good usage of network resources by achieving a better average delivery rate and a lower end-to-end delay
