Delay Analysis And Optimality Of scheduling In Multi-hop Wireless Network

The delay is one of the important metric considered in the wireless network and wire-line network.In single hop wire-line network only one hop(router) is present from source to destination .In single hop network the interference problems occurred and the trac control is dicult,the high amount of delay and the low amount of packet delivery ratio, because of routes changes dynamically and finally leads to low performance of the network.The delay analysis of a packets plays a vital role in the network.In real time applications the fixed time is given, so that the given amount of time all the packets should be delivered from source to destination.In multi-hop wireless network decomposition of packets into multiple paths,if any two nodes meet at same point bottleneck is occurred.In order to overcome from bottleneck used new queuing technique.For knowing the behavior of the each path in the network lower bound analysis is used.Dierent policies are used for scheduling the packets, which gives better optimality
