Abstract

The wireless sensor network (WSN) has emerged as a new information and data gathering paradigm based on the collaborative efforts of a large number of autonomous sensing devices. Consequently, the wireless sensor network is variously being deployed in civilian application areas, including environment and habitat monitoring, healthcare applications, home automation, and traffic control. In addition, it supports various desirable functions for sensor networks including: ease of installation, self-identification, self-diagnosis, reliability, and time awareness for coordination with other sensor nodes. These reasons increased the consumption of wireless sensors network, and WSN will take an important place in pervasive computing. Despite the increased range of potential application frameworks, the security gap between existing Wireless Sensor Network designs and their requirements of security sensor network applications remains unresolved. With small memories and processors, limited energy and tiny packets, sensor networks cannot afford luxury of traditional security solutions; this limitation causes security threats. There are several important security challenges, including access control, message integrity and confidentiality, and trust solutions that require us to use a careful design of resource constraints for pursuing more enhanced security solutions for a wireless sensor network. In this thesis, we present an analysis of various current WSN security mechanisms, and we have also introduced a new idea of persistent security solutions that support trust within security in all of the general purposes of a Wireless Sensor Network area and conclude with future research challenges
