Location-Based Multicast Routing Algorithms for Wireless Sensor Networks in Presence of Interferences
Location-based Multi-cast Routing (LMR) technique can increase the lifetime and the channel capacity of Wireless Sensor Network (WSN) by reducing the number of duplicated data transmissions and control messages. Previous LMR algorithms can suffer performance deterioration in real deployments because they consider only location of nodes and can transmit packets across concrete walls or other interfering object. To tackle this problem, the authors propose an interference-aware location-based multi-cast routing algorithm for WSNs. In the proposed algorithm, each node adjusts the energy cost for each link adaptively considering the interference effect and uses it for multi-cast decision in order to minimize the interference impact.
