Abstract-Source-destination pairs in wireless sensor networks often have multiple shortest hop paths because the nodes are densely deployed. These multiple paths provide a great opportunity to reduce delay as well as energy in an asynchronous dutycycled network. In this paper, we exploit the redundancy available at the route layer using MAC-layer anycasting and reduce the delay incurred at each hop as the sender waits for its next hop node to be awake. By applying anycast to existing X-MAC and NPM protocols, we show that anycast can be incorporated into duty-cycled MAC protocols by using small modifications. Our evaluations in ns-2 show that the modified X-MAC and NPM protocols can achieve delay improvements of 30% and 12% respectively by exploiting the route level redundancy using anycast.
