A 3-Tier Heterogeneous Secure Routing Protocol for Wireless Sensor Network
Source: Kurukshetra University
Security is very critical parameter in sensor networks. Securing the WSN needs to make the network support every security property. Security attack is a concern for wireless sensor networks because of usage of very low capacity devices in the systems and physical accessibility to sensor nodes. Therefore to prevent confidential information from being stolen, it is important to provide secure communications between sensor nodes and base stations. This paper presents, a 3-tier heterogeneous secure routing protocol based on LEACH. This protocol is free from all threats which are based on the identity crisis.
