An Inconventional Lightweight Freshness Scheme for Wireless Sensor Networks

Sayyed Johar, Manjula G R, Namitha M V: An Inconventional Lightweight Freshness Scheme for Wireless Sensor Networks. In: International Transaction on Engineering & Science, 1 (3), pp. 27-45, 2019.

Abstract

This paper presents an in conventional lightweight freshness scheme for wireless sensor networks, which refreshes the key without inter node message transmission, secret key establishment and freshness are challenging task in resource constrained wireless sensor networks (WSNs). A large number of messages are exchanged for key establishment at startup and every time a node join or leave the group to refresh keys. These operations incur huge computation and communication cost that reduces the network life time. The aim of the project is to minimize energy consumption and improve network lifetime that presents a XOR based key freshness scheme which allows refreshing the key without inter node message transmission. A single message containing a magic word is transmitted by the group head to its member nodes and keys are refreshed using XOR. This only requires a light weight message from a more powerful head node and thus eliminates the inter node communication cost.
