Wireless sensor networks applications involve a position of inaccessible metropolitan vicinity en-closed by wireless sensor nodes (WSNs)-monitors environmental parameters like battle field surveillance, home applications like fire alarm, health monitoring, etc. Energy plays a vital role in Wireless sensor networks. So, we have to concentrate more on balanced energy consumption for maximizing the network lifetime. Minimizing the whole network overhead and vigor disbursement coupled with the multi-hop data reclamation process that ensuring balanced energy consumption among SNs which results in prolonged network lifetime. This can be achieved by forwarding the sensed data to their cluster heads and then filtering the data before sending it to their tryst nodes, which is located in proximity to MS’s trajectory. Sleep and awakening of nodes periodically helps to retain their energy for some more time. The events occurring in any part of the network should be identified by the nodes, while arrangements sleep and active among the nodes. (i.e.) the nodes should be scheduled to sleep, so that the outstanding nodes can take care of the whole network. The eXtensible Randomized Matrix Arithmetic Coding (XRMAC) Technique has been used to enhance the security among all the nodes in the network. Simulation results show that our Proposed Scheme can have better Lifetime, improved throughput, reduced delay compared to other existing methods.

In wireless sensor networks new challenges appear when we target a large-scale sensor network as scalability issues arise in dense sensor networks where multiple sources need to communicate with multiple *** protocols are always being developed to tackle the efficiency in routing and power *** Proximity Based Data Dissemination "PBDD" approach aims to provide high efficiency in data dissemination from multiple sources to multiple mobile *** proposed model reduces the communication overhead between source,and sinks through eliminating most of the nodes from joining in the dissemination *** source builds its own grid structure while being location unaware and the sinks send their queries throughout the field to request data while updating their positions when they are on the move which will enable them to continuously receive data while *** performance of PBDD is examined through analytical equations and is found to perform best in high dense large scale networks in comparison to other dissemination models.
