A Novel Approach to Find Optimal Path by using Firefly Routing Algorithm in WSN

Wireless Sensor Networks are appropriate for many applications such as agriculture, smart phones, automation and disaster reduction. In general, medium access control protocol (MAC) plays a vital role in WSN by informing the network when and how to access a medium and as a result it reduces the energy consumption. In wireless sensor networks in the star topology consistent 802.15.4k standard in which sensors could neglect to report detecting data to the get to point because of impermanent checks that disorder the connection with the access point. In this paper we discuss the connectivity and information loss of wireless environments. We categorize the work First; we study general connectivity requirements in relay networks. Second, to avoid information loss and to restore the proper connectivity. It can be performed by firefly algorithm with localizability aided localization protocol (F-LSL). It depends on the device of stochastic geometry and specifically, on Poisson direct procedures toward look for the tradeoff, which emerges from the determination of a subset of transfer hubs and the vital transmitted power that transfers need to use to reestablish arrange network.
