Routing protocol for virtualization of Wireless Sensors Networks

Our developed protocol Energy Aware Mesh Routing EMRP is a robust, cluster-based routing technique used in Wireless Sensor Network (WSN). It can provide a reliable, scalable, energy efficient multipath routing mechanism for data transmission to Base Station (BS). This scheme is also classified as a routing technique supporting virtualization WSN (VSN) as it can share network resources between different VSNs for achieving resource efficiency. In this paper, we propose a new dynamic switch process for EMRP that use the current energy value of relay and backup node and evaluate the performance of new switch strategy in terms of total residual energy, load balance, network lifetime and rate delivery compared with the old scheme. Via simulation, we realize that the newEMRP protocol can achieve better rate delivery and load balance than EMRP. Furthermore, we analyze and evaluate an application case of virtualization in OMNET++ that utilizes our two routing algorithms in order to investigate the capability of collaboration and network resource sharing between different VSNs. Our simulation result shows that both schemes can achieve collaboration and efficient network resource sharing for the purpose of virtualization. More concretely, the newEMRP protocol can achieve better capability of network resource sharing than the old protocol.
