Review of Heterogeneous/Homogeneous Wireless Sensor Networks and Intrusion Detection System Techniques

, and . (2014)

Abstract

Wireless sensor networks are made up of number of tiny mobile nodes, which have the capability of computation, sensing and wireless network communication. The energy efficiency of each node in such kind of networks is one of the important issues under consideration. Thus for these networks, sensor nodes life time is basically depends on use of routing protocols for routing operations in WSN. There are various routing protocols propo sed by different researchers, which are considered as efficient on the basis of performance of network lifetime and energy scavenging. There are different routing protocols introduced for WSN such as flat routing protocols, clustering routing protocols, hi erarchical routing protocols etc. On the other hand, there are basically two types of WSNs, homogeneous and heterogeneous sensor networks. As WSN is vulnerable to different types of security threats, there are many security methods presented with their own advantages and disadvantages. Most of security methods are applied only on homogeneous WSN, but recently some methods were presented to provide the routing security in heterogeneous WSNs as well. In this paper, the different security threats and Intrusion s in WSNs are presented, with review of different security methods .
