Background:
The performance of the network protocol depends on number of parameters
like re-broadcast probability, mobility, the distance between source and destination, hop count,
queue length and residual energy, etc.
Objective:
In this paper, a new energy efficient routing protocol IAOMDV-PF is developed based
on the fixed threshold re-broadcast probability determination and best route selection using fuzzy
logic from multiple routes.
Methods:
In the first phase, the proposed protocol determines fixed threshold rebroadcast probability.
It is used for discovering multiple paths between the source and the destination. The threshold
probability at each node decides the rebroadcasting of received control packets to its neighbors
thereby reducing routing overheads and energy consumption. The multiple paths list received from
the first phase and supply to the second phase that is the fuzzy controller selects the best path. This
fuzzy controller has been named as Fuzzy Best Route Selector (FBRS). FBRS determines the best
path based on function of queue length, the distance between nodes and mobility of nodes.
Results:
Comparative analysis of the proposed protocol named as "Improved Ad-Hoc On-demand
Multiple Path Distance Vector based on Probabilistic and Fuzzy logic" (IAOMDV-PF) shows that
it is more efficient in terms of overheads and energy consumption.
Conclusion:
The proposed protocol reduced energy consumption by about 61%, 58% and 30% with
respect to FF-AOMDV, IAOMDV-F and FPAOMDV routing protocols, respectively. The proposed
protocol has been simulated and analyzed by using NS-2.
