Abstract
In this paper, the analogy between the optimal routes within a sensor network and the electrostatic field lines is utilized successfully. In other words, partial differential equations similar to those of the electrostatic field theory are solved using Finite Difference Method (FDM) to find the optimal routes of the network. For the purpose of validation, an Opnet program based on the generated optimal routes is written to find the throughput and delay of the sensor network, a similar program is then applied to some arbitrary routing scenarios. The results show that the throughput and delay performance of the proposed method is better than that of the chosen arbitrary routing scenarios. It is also found from the results that the throughput of some scenarios is 50 % lower than that of the proposed method.

Sensor networks consist of nodes, which are distributed over an area in order to perform a special task
The results given are based on the following assumptions : 1- The sensor nodes are distributed over an area 1 Km × 1 Km. 2- The number of source nodes is equal to (440) while the number of destination nodes is only one. 3- The central node is responsible about forwarding the data of the whole network to the main processing unit to process it and to decide the suitable action
Summary
Sensor networks consist of nodes (smart devices), which are distributed over an area in order to perform a special task. It is worth to mention that the central unit is used to collect data from all sensors mainly for processing and archiving functions. 4- The paths between the positive and negative charges represent the minimum energy routes. 4- The shortest paths between the sensors and destinations represent the minimum delay routes. If the initial distribution of sources and destinations is not given, it is possible to locate sources and sinks within a given area freely, the location that reduces the number of nodes required to support the flow of information will create a routing pattern identical to the electrical field lines created in a similar Electrostatics topology.[1],[2],[7]
