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.
