A Performance Analysis Of Backbone Structures For Static Sink Based Starfish Routing In Wsn

Time sensitive applications in Wireless Sensor Network (WSN) with a static sink are emerging rapidly. The main challenges of these applications are to achieve higher throughput with lower delay and less power consuming routing protocol development for realistic environment. To overcome the challenges, backbone based routing protocols are lucrative for guaranteed data delivery in WSN. The backbone of Starfish routing protocol with a ring and radial-canals employs more nodes to construct the backbone but suffers from congestion and interference within the network. It also leads to lower throughput and higher delay. In this paper, the basic Starfish routing is modified as Angular Starfish routing backbone structure and furthermore is improved to Parallel Starfish routing backbone structure. A realistic wireless signal propagation model has been used to implement the simulations. The results show that the Parallel Starfish routing protocol outperforms state-of-the-art works in terms of throughput, delay and energy consumption.
