Multi-geocast Algorithms for Wireless Sparse or Dense Ad Hoc Sensor Networks
Nassima Hadid, Jean‐Frédéric Myoupo · 2008
Multi-geocasting in wireless sensor network and ad hoc network is the delivery of packets from a source (or sink) to all the nodes located in several geographic areas. The objectives of a multi-geocasting protocol are guaranteed message delivery and low transmission cost. All the existing protocols guarantee delivery only in dense networks. In this paper, we present two multi-geocast protocols which guarantee delivery of the packets whatever is the density of the sensor network (dense or sparse). They are also suitable for networks with irregular distributions with gaps or obstacles.
