Technical Studies, Analysis Of Sensor Networks Based On Network Coding Energy

In traditional wireless sensor network, relay nodes only transmit the packets .But when it is integrated with network coding, the relay nodes will code the packets first, then transmit them .The sensor network with network coding, can obviously advance SDR. At the same time, relay nodes with the scheme called the best nodes' distance deployment will effectively balance the consumed energy and raise the life span.This essay applies the scheme called the best nodes' distance deployment to the multi-path routing model based the network coding. And another scheme supposed the nodes in the same distance are also applied to the model. Then we compare the differences between the same models with different schemes. Next, we observe the performance of multi-path model with the same schemes which are used previously. According to two criterions (SDR and nodes' consumed energy), we find the multi-path routing model based the network coding with the best nodes' distance deployment scheme is the best.In light of the way that is used in the best nodes' distance deployment in single path, we bring up the plan in the multi-path, and compare the two on the condition of the nodes in the same distance scheme. We do a deep analysis about the network model with random linear network coding technology. Compared it with multi-path model, we could find out that multi-path routing model based on the network coding have a better performance in SDR. At the same time, we compare the model with the best nodes' distance deployment and the nodes in the same distance.Both on theory and simulation results, it turns out that the multi-path routing model based the network coding has a better performance in SDR. The best nodes' distance deployment has been brought up which could balance the nodes' consumed energy and extend the life-span.
