Performance Evaluation of a standard reliable, fault tolerant Software Defined Wireless Sensor Network with an extended early inactive problem

Nowadays, in this modern era, wireless communication is gaining considerable increase in importance over the existing traditional networks and has become the main part of any network architecture. Among them, Software Defined Network (SDN) has gained more priority alongside wireless sensor networks. This results to form a type of typical network i.e. Software defined wireless sensor network (SDWSN). In this scenario, Energy efficiency, increased throughput and data delivery rate are the main goals to be achieved and evaluated to measure the performance of the network. Further, to achieve this transmission reliability in the network, we need to employ fault resilient, reliable and fault tolerant wireless data transfer in the network. Additionally, to achieve transmission reliability, traditional fault tolerant-MAC (FT-MAC) and Reliable timeout-MAC (RT-MAC) protocols in WSN [1] [2] is proposed to satisfy the requirements for the appropriate schedule of routine work and to achieve the final output. In this paper, we have investigated the optimization process in the form of the extension of passive inactiveness problem in certain topologies to evaluate the delay in packet delivery and to measure the reliability of the network. In order to achieve the solution for this problem, here we propose a fault tolerant, reliable extended timeout MAC (FTETMAC) protocol that guides the forwarded connecting nodes to final output state and reschedules synchronization in the form of time management. According to the simulation results our proposed FTETMAC protocol achieves better reliability, high throughput and energy efficiency compared to the other traditional MAC protocols along with their components.
