Query based multicast Routing algorithm in Wireless Sensor Networks by learning automata

A wireless sensor network consists of a large number of sensor nodes which are deployed over an area toperform local computations based on information gathered from the surroundings. Each node in the network isequipped with a battery that one of the most challenges in these types of networks is Energy limitation whichhas direct influence on sensor network lifetime. Multicast routing in wireless sensor networks is a way for datadelivery to several destination s. In this paper we are intended to present a multicast routing algorithm inwireless sensor networks, and we make virtual backbone out of Minimum Steiner Connected Dominating Set(MSCDS). This virtual backbone is initiated according to Energy level, Neighboring, and distance from Sinknode. So, to this end we use an algorithm based on learning automata named MQMSCDS-LA deal with themulticast routing problem. Finally, we simulate proposed method by ns2 simulator. Thus the results show highperformance of the proposed algorithm.
