Efficient Resource Allocation in Multicasting over Mobile Adhoc Networks


A Mobile Ad-hoc Network (MANET) represents an ad-hoc network which are able to change locations; which can also perform self-configuration and self-organization in a dynamic environment. Group communication system plays a major part in MANET environment which are implemented by multicasting method which provides delivery of packets to a group of destination. But there are many difficulties in implementing scalable, optimized and efficient multicasting network in mobile ad-hoc network because managing a dynamic environment with group membership is a challenging process. Efficient Geographic Multicast Protocol (EGMP) is proposed which uses a virtual zone base structure. The geographic region is divided into many virtual zones. The Distance between the source and other nodes in the group are found and the one closest to source is chosen as cluster head or zone leader. Zone leader communicates with its group members. Only zone leader transmits data and hence the node does not receive the same packets again and again. EGMP greatly simplifies zone management and packet forwarding. EGMP uses geographic forwarding to provide reliable packet transmission. It ensures the successful transmission of the data packets, has low overhead and reduced redundant packet transmissions. Compared with Scalable Position Based Multicast (SPBM), simulation results of EGMP shows high packet delivery ratio thus packet missing while transmission are reduced hence re-transmission of packets are reduced and bandwidth is utilized efficiently.
