Abstract
In this paper, we propose a path redundancy based security algorithm (PRSA) to improve routing security in wireless sensor network. The algorithm uses alternative routing paths for each data transmission call to overcome the sensor network attack. To enhance network reliability, PRSA allows sensor node data to be sent on defined routing paths using various transmission modes including round robin, redundant and selective modes.
PRSA performance is studied and analyzed via simulation, for a network that is comprised with one of typical sensor network attacks and with a variety of input parameters. Various performance measures were evaluated including: network delay, transmission cost, complexity, energy dissipation and throughput. The performance results proved that the algorithm improves significantly sensor network resistance to common sensor network attacks.
