Wireless sensor networks (WSNs) have gained much attention in today’s research domain for supporting a wide variety of applications including the multimedia applications. Multimedia applications that are regarded as the quality-of-service (QoS)-aware, delay sensitive, and bandwidth hungry applications require enough energy and communication resources. WSNs being the energy-scarce network have now...
In a resource constrained wireless sensor network (WSN), communication tasks can be expensive in terms of power consumption. Thus, when good communication is required, a mechanism that can maximize the chances of a successful transmission of information via wireless network is very desirable. The Opportunistic Routing (OR) protocol has been proposed as an alternative and efficient method for exploiting...
Several geographic (or position-based) routing protocols have been proposed for data dissemination in wireless sensor networks. In these protocols, routing is based on the positions of neighboring nodes. In particular, the next-hop node is selected according to either a distance-based strategy, which favors a neighbor with the largest distance progress toward the sink, or a direction-based strategy,...
