Optimizing the Hybrid Approach for Time Synchronization in Wireless Sensor Networks

There are various approaches to achieve time synchronization in case of wireless sensor networks. Amongst them "sender to receiver" and "receiver to receiver" are the frequently used approaches for synchronizing time. Both the methodology has some drawbacks with respect to number of message exchanged for synchronization. To overcome those drawbacks Hybrid approach was introduced. Hybrid approach is efficient with respect to number of message exchanged compared to both methodology. In this paper Hybrid Approach is improved, to reduce the message communication that is required to synchronize time between the nodes in sensor network.
