摘要：The performance of Wireless Mesh Networks is not optimal by using the conventional layered protocols (TCP-IP). Then the method of optimization at different layers of the protocol stack (TCP-IP) can help to achieve optimal network performance. This method usually results in a clean-slate protocol architecture that is different from the protocol architecture of WMNs. Such a difference actually demonstrates the need for a cross-layer design. Specific features pertaining to WMNs also show the need for cross-layer optimization across different protocol layers. In this paper, the need for cross layer design in WMNs is discussed first. Later in this paper we will discuss the different cross layer optimization schemes and we will compare the performance metrics such as throughput, end-to-end delay and PDR(packet delivery ratio) in multihop wireless sensor networks with and without user cooperative diversity.
