A novel clustering with scheduling technique to enhance capacity in multicast MANET

Abstract

Mobile Adhoc Network(MANET) consists of mobile nodes in which all nodes can communicate with each other nodes in the range of radio transmission through wireless channel. Each node can act as a sender, a receiver or a router. As a sender, the node can send message to the specified destination node through some route. As a receiver, it ll receive the message from various nodes. As a router, it ll relay the packet to the destination or next router among the route necessary. Each node will buffer packets once the packets ought to wait for transmission. In MANET mobile node is also laptop, PDA, mobile phone or packet pc with wireless connectivity. MANET does not rely on a pre-existing infrastructure, like routers in wired networks or access points in managed(infrastructure) wireless networks. The suburbanized nature of wireless network makes them applicable for a verity of applications once central nodes can t be relied on and can improve the quantifiability of MANETs compared to wireless managed networks. Marginal configuration and fast preparation create MANETs applicable for emergency things like natural disasters or military conflicts. A key research challenge in MANET is to extend the efficiency of information transfer, while handling the harsh environmental conditions such as constrained and highly mobile devices. Multicasting plays an important role in the typical applications of MANET, namely emergency search and rescue operations and military communications. In such an environment nodes from groups to carry out certain tasks that require point to multi point voice and data communication. A source is sending the same data to a certain set of nodes in the network. newline
