| Abstract: | LEPS is a multi-hop routing protocol in wireless sensor networks.In LEPS,a tree topology is set up,where the sink node is the root node.The nodes send data to their parents along the shortest path.In this paper,we use a simulation tool of TinyOS—TOSSIM to evaluate the performance of LEPS.Specifically,we study the network routing set-up time,the control overhead and the packet transfer delay with different values of control packet sending interval.The results show that as the sending interval of control packets increases,the network routing set-up time gradually extends and both the network control overhead and statistical average of packet sending delay are decreasing.As a result,control packet sending interval should be carefully chosen according to the requirement of the network. |
