摘要：In today's world emerging applications of wireless sensor networks (WSNs) require real-time Qos. average delay and end to end delay distribution is important in WSN S . In a typical delay monitoring WSN S , multiple reports are generated by several nodes when a physical event occurs, and are then forwarded through multi-hop communication to a sink that detects the event. To improve the delay detection reliability, usually timely delivery of a certain number of packets is required. The previous delay analysis papers fail to give the single hop delay distribution, also the busty traffic is not considered so in this paper, a comprehensive cross-layer analysis framework is used. The simulations on Network Simulator 2 show the average and end to end delay for both deterministic and random deployments. Our model gives closed form expressions for obtaining the average delay and End to End delay characteristics and models each node as a discrete time queue. Moreover, the simulation and experiments show the Throughput and the packet loss in WSNs. In this paper, the comparison of the CSMA/CA Mac protocol and cross layer protocol for average delay and End to end dealy,Throuhput and Packet loss is done for WSNs.
