“Designing a Multi Hop Secured Reactive Routing Protocol for Heterogeneous Wireless Sensor Network using Clustering”

In the wireless sensor network we used hundreds of sensor node. If energy, range and hardware capabilities are different in various nodes in the network than these types of network are mainly known as heterogeneous network. It is noted that, to maintain a reliable information delivery, data aggregation and information security that is necessary for efficient and effective communication between these sensor nodes. Only concise information should be delivered to the sink nodes to reduce communications energy which help to increase the effective network lifetime with optimal data delivery to base station and end user. An inefficient use of the available energy of nodes leads to unreliable performance and short life cycle of the sensor network. Energy in the sensors is a scarce resource and must be managed in an efficient manner to expand the life of network. We want to design a secure multi-hop reactive protocol for heterogeneous wireless sensor network with clustering.
