Object tracking is an important application in wireless sensor networks. To get the accurate location of a given object timely, designing an efficient routing protocol and incorporating it with the location response is the key. While limits of wireless sensor networks propose challenge for the routing of object tracking. This paper constructs a cluster-based routing tree, which makes balance between...
Routing in wireless networks has been heavily studied in the last decade and numerous routing protocols were proposed in literature. The packets usually follow the shortest paths between sources and destinations in routing protocols to achieve smallest traveled distance. However, this leads to the uneven distribution of traffic load in a network. For example, wireless nodes in the center of the network...
While extensive studies have been carried out in the past several years for many sensor applications, the main approach for sensor networking cannot be applied to the sceonarios with extremely low and intermittent connectivity, dubbed the Delay/Fault-Tolerant Mobile Sensor Network (DFT-MSN). Without end-to-end connections due to sparse network density and sensor node mobility, routing in DFT-MSN becomes...
Energy aware routing protocols are consistently cited as efficient solutions for ad hoc and sensor networks routing and data management. However, there is not a consistent approach to define the energy related cost metrics that are used to guide the routing protocol performance. This paper provides a survey and analysis of energy related metrics used for ad hoc routing. First, the most common energy...
