Synchronization in wireless sensors networks using balanced clusters

The advent of smart devices and continuous expansions of smart environments make Wireless sensor networks (WSNs) an important part of our daily lives. The usage of a myriad of devices in self-organizing networks in a various fields such as home monitoring, medical and military etc. requires an efficient delivery of sensed information. For this necessity, a local clock of sensors nodes needs to be synchronized and up-keep timely synchronization between sensors, to ensue seamlessly communication with each other via radio links aimed at sharing and treatment of reliable information. In this paper, we present balanced Timing-sync protocol for sensor networks that aims at providing network-wide time synchronization in a sensor network. Our schemes work in two steps. In the first step, a hierarchical structure is established in the edges of this structure to establish a global time scale through the network. Ultimately all node in the network synchronize their clock to a reference node. We implement our algorithm on NS2. We argue that our algorithm roughly gives better performance as compared to the work in the same line of research like TPSN.
