Research on Multicast Routing Protocol in Wireless Sensor Network

Wireless sensor network is a revolution of information collection and perception field, which has been draw much more application gradually. However, The WSN with characteristic of self-organization, multi-hop, dynamic topology and limited energy resources, which make the network to prolong it´s lifetime become extremely difficult. This paper analyzed variety multicast protocols in existence and the current achievements in the research based on a comprehensive studying of a mess of multicast routing protocols. This document provided the appropriate application environment for types of multicast protocols and the specific improvements. It has an active significance for WSN to increase it´s performance in the near future.
