Security Schemes in Wireless Sensor Networks with Mobile Sink

Abstract

Wireless Sensor Networks (WSN) has become ubiquitous and pervasive in many newlineapplications. A typical sensor network may include hundreds to several thousands of sensor newlinenodes that are of low rate and contain limited computation power and energy consumption. newlineThe objective is to focus on a sensor network that uses mobile sink to gather sensor data. newlineSecurity is a vital issue when sensor networks are deployed in unsympathetic environment newlinewhere they are exposed to a variety of malicious attacks. An adversary can easily monitor the newlinetraffic, capture the sensor nodes, impersonate a mobile sink to gather sensor data and provide false newlineinformation. The destination of messages is the mobile nodes that are originated by sensors. The newlinesensor nodes are static and densely deployed in the sensing area. One or multiple mobile sinks newlinemove throughout the network to collect data from all sensor nodes. newlineThis research work primarily focuses on security routing with mobile sink based on newlineWSN considering the various limitations. Some of the major reasons for security failures have newlinebeen analyzed to design solutions for the same. The security issues have drawn a major attention newlinein this research work, which aims to design a WSN that provides secure routing. The proposed newlinemethods perform a new secure routing with mobile sink in WSNs. The first of the three methods newlineis the Layered Refuge Framework to avoid static node replication attack for WSN with Mobile newlineSinks. This scheme is used to provide authentication between static points and sensor nodes. It newlineprovides complete security against access point replication attack, maximum throughput and route newlinethe data packets securely in WSNs. The second method is a Secure Localized Sensor newlineReprogramming Protocol (SLSRP) with Mobile Sink for WSN. This scheme proposes a new newlinesecure routing which can securely discover the route between the pair of nodes in the WSN. It newlineallows the base station to authorize multiple network users with different privileges to newlinesimultaneously and directly disseminate data items to the sensor nodes. It reduces packet loss rate newlineand delay. It provides better packet delivery rate and throughput by adding the SLSRP in the newlinemobile sinks. The third method is Hermitian Matrices based Security Scheme with Mobile Sink in newlineWSN. This scheme provides the security with One Time Key (OTK). It proposes the method of newlinedata transfer through matrix method uses complex numbers and its conjugate in finding the newlineintended node to send the data. It fits well over the communication area in the network. newline
