Various types of routing protocols in Wireless Sensor Network with vulnerabilities: A review

Wireless Sensor Network (WSN) is made of a large number of sensor devices where the mode of communication is done over wireless media. Advancement in this field of application opens the path of availability of small and low costing sensors which are involved in different types of physical and environmental condition states, data process management and communication in the wireless media. WSN provides a large scale of sensor nodes which have transmission in the limited scale, along with their limited process, storage and energy availability through the clustering techniques, thus provides new and efficient way towards the prolonged lifetime of WSN system. It provides lot of its applications in the fields of military and health. Though the sensor networks are restricted towards resource utility, the network system becomes the open threat towards different types of traditional attacks. But the conventional techniques fail to find its way from security threats due to the limited resource availability in these types of networks. As a result of it, the security in WSN model becomes an important and challenging task in the research field due to inherited limitations of sensors itself. In this paper we are highly focused on the discussions on different type of attacking scopes in Wireless Sensor Network followed by the security description, analysis of routing protocols in terms of attacks and security goals, which concludes in some simulation results of the stated protocols with their merits and demerits.
