Scarcity of resources is a major issue in wireless sensor networks. Routing is one of the areas which plays important role to manage the scarcity of the resources. To address the resource scarcity issue, the authors propose a heuristic model Single Path Position Based Multicast Tree (SPPBM). The Single Path Position Based Multicast Tree model is based on geographic (position based) routing. This network model contains nodes with one node works as Access Point, where an access point is selected as a gateway. The performance comparison is done with other available multicast routing techniques.
