HOW NETWORKS ARE USED IN BATTERY LIFE TIME AND DISTANCE MANAGEMENT?

<font color=#000080>Mobile adhoc </font>network, an autonomous system is a collection of wireless nodes that can dynamically be set up anywhere and anytime without using any pre-existing network infrastructure. To broadcast the data packets to the nodes (typically powered by batteries with a limited energy supply) of the entire ad-hoc network, flooding mechanism is used.
However, the excessive use of flooding generates a large number of redundant packets, and it gives heavy traffic load to the network. To broadcast the data packets in a much effective way, redundant rebroadcast must be reduced thereby performing the high message reachability.
For MANET, a broadcast is an important issue, which should deliver the packets throughout the network with high reachability, low network load and low latency. Relay nodes are a subset of the one-hop neighbors of the node, which can establish communication paths with all two-hop neighbors are responsible for forwarding the broadcast message upon receiving it for the first time, while non relay nodes will not forward the message.
