Abstract
This paper comparatively analyzes the performance of X-MAC and PW-MAC as asynchronous sensor MACs with tree-topology using virtual simulation. PW-MAC has better performance in comparison to X-MAC, but it is receiver-initiated and shows collision when data is sent to common receiver. Therefore, this study evaluates whether PW-MAC maintains better performance in tree topology having common receiver for all transmissions. The result of simulation on NS-2 showed better performance of PW-MAC than X-MAC in tree-topology.
