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.
