Operator calculus approach for route optimizing and enhancing wireless sensor network
Route optimization is one of important feature in wireless sensor networks in order to enhancing the life time of
WSNs. Since Centrality is one of the greatest challenges in computing and estimating the important node
metrics of a structural graph, it is necessary to calculate and determine the importance of a node in a network.
This paper proposes an alternative way to optimizing the route problems which is based on multi-constrained
optimal path (MCOP) and operator calculus approach. A novel routing protocol called Path Operator Calculus
Centrality (POCC) is proposed as a new method to determine the main path which contains high centrality
nodes in a wireless sensor network deployment. The estimation of centrality is using the operator calculus
approach based on network topology which provides optimal paths for each source node to base station. Some
constraints such as energy level and bit error rate (BER) of node are considered to define the path centrality in
this approach. The simulation evaluation shows improved performance in terms of energy consumption and
network lifetime
