Improving performance of on demand multicast routing by using fuzzy logic

Abstract

A Mobile ad hoc network is a collection of wireless communication nodes that dynamically organize themselves to form a network without the need for any fixed infrastructure or centralized administration. Multicasting can be considered as an efficient way to deliver information from source nodes to several client nodes. Although multicast routing algorithms are desirable, their forwarding structure and network resource consumption makes them significantly less efficient than unicast routing algorithms. In this research, a fuzzy-based policy was used to improve performance of On-Demand Multicast Routing Protocol. The main goal of FBODMRP is to establish a small, high quality and efficient forwarding group. An evaluation shows that our approach increases packet delivery rate by up to 40%, reduces average end to end delay and consumed power by about 35% and 45% respectively.
