Energy Efficient Data Tranfer in Secure Wireless Sensor Networks

Wireless sensor networks are a new type of networked systems, characterized by severely constrained computational and energy resources, and an ad hoc operational environment. Wireless sensor networks(WSNs) have been increasingly available for large-scale applications in which energy efficiency & security is an important performance measure. Driven by the energy & security limitation nature of WSNs lots of research works have been done in aspects such as nodes replication, data aggregation routing, security moniroting etc. In this paper we first study the flooding algorithm and then remove limitation of flooding algorithm using grid network. Then we propose a Horizontal -- Vertical method for load balancing of the grid network.
