Wireless Sensor Networks (WSN), Mobile Ad-Hoc Networks(MANET), Routing Protocols,Threats and Security Attacks.
A Mobile Ad hoc Network (MANET) consists of a collection of wireless mobile nodes that are capable of communicating with each other without the use of a network infrastructure. Wireless Sensor Networks (WSN) have become a growing area of research and development due to the tremendous number of applications that can greatly benefit from such systems and has lead to the development of tiny, cheap, disposable and self-contained battery powered computers, known as sensor nodes or ―motes‖, which can accept input from an attached sensor, process this input data and transmit the results wirelessly to the transit network. Routing is a basic step for dataexchange. In wireless ad-hoc networks each node acts as a router and executes a routing protocol. Wireless ad-hoc networks are highly resource constrained in terms of network topology, memory and computation power. The reliable data transfer is a difficult task in mobile ad-hoc networks because of resource constraints. Despite making such sensor networks possible, the broadcasting nature of the sensors presents a number of security threats when deployed for certain applications like military, surveillances etc .The problem of security is due to the wireless nature of the sensor networks and constrained nature of resources on the wireless sensor nodes, which means that security architectures used for traditional wireless networks are not viable. However, wireless MANET is particularly vulnerable due to its fundamental characteristics, such as open medium, dynamic topology, distributed cooperation, limited bandwidth and limited battery power. Generally, routing security in MANETs appears to be a problem that is not trivial to solve. It is observed that the routing attacks have severe impact on MANET than WSN. In this paper we discuss some routing attacks and challenges faced by WSNs and MANETs and also add some secure routing protocols.
