Abstract: As most applications in Wireless Sensor Networks (WSN) are location sensitive, in this paper, we explore the problem of location-aided multicast for WSN. We present four strategies to construct the GeoMulticast routing tree, namely, SARF, SAM, CoFAM and MSAM. Especially, we discuss CoFAM in detail and give the algorithm for setting up a multicast tree in a cone-based forwarding area. This algorithm is distributed and energy-efficient. Extensive simulations have been conducted to evaluate the performance of the proposed routing schemas. Simulation results have shown that when constructing a multicast tree, fewer messages must be transmitted in our schemas.
