Security is a major concern for protected communication between mobile nodes in a hostile environment. In hostile environments adversaries can bunch active and passive attacks against intercept able routing in embed in routing message and data packets. In this paper, we focus on fundamental security attacks in Mobile adhoc networks. MANET has no clear line of defense, so, it is accessible to bo...

Wireless Sensor Networks (WSNs) can be used for various applications, such as military, environmental, health, home, and other commercial applications. Since thousands of sensor nodes are densely deployed, and they are based on mobile ad-hoc networks, a secure routing scheme become a critical and challenging issue to WSNs. Recent advances in WSNs have led to many new protocols designed for secu...

Mobile Ad hoc Networks (MANET) due to its unpredictable topology and bandwidth limitations are Vulnerable to attacks. Establishing security measures and finding secure routes are the major challenges Faced by MANET. Security issues faced by ad hoc networks are node authentication, insider attack and Intrusion detection. Implementing security measures is challenging due to the presence of limite...

Wireless sensor networks (WSN) have lot of interest in research due to their wide range of typical application areas such as environmental, military and commercial enterprises. High efficient routing is an important issue for the design of wireless sensor network (WSN) protocols to meet the severe hardware and resource constraints. Sensor network possesses unique challenges to protocol builders...

The infrastructure of a Mobile Ad hoc Network (MANET) has no routers for routing, and all nodes must share the same routing protocol to assist each other when transmitting messages. However, almost all common routing protocols at present consider performance as first priority, and have little defense capability against the malicious nodes. Many researches have proposed various protocols of high...

This paper studies the problem of robust spectrum-aware routing in a multi-hop, multi-channel Cognitive Radio Network (CRN) with the presence of malicious nodes in the secondary network. The proposed routing scheme models the interaction among the Secondary Users (SUs) as a stochastic game. By allowing the backward propagation of the path utility information from the next-hop nodes, the stochas...

The link state routing protocol is the most widely used intra-domain routing protocol, which is used to distribute and maintain routing information among various routers within a domain. Unfortunately, this protocol is vulnerable to several security attacks. These attacks may be as simple as packet sniffing or as sophisticated as the insider attack. Research has been done to enhance the securit...

Lifetime optimization and security are two important design issues for WSNs with nonreplenishable energy resources. Routing protocols in wireless sensor networks (WSNs) are susceptible to a number of attacks depending on the nature of the protocol, its application, and the environment in which the protocol is intended to be used. Routing protocols that do not take the malicious attacks into acc...

Wireless ad hoc network is a special kind of wireless network with a dynamic topology consist of self organized nodes. The nodes in the networks are randomly and frequently. Due to the self organizing and decentralized capabilities, ad hoc networks are used for a wide range of civilian and military applications. Wireless ad hoc networks are an open environment and it is susceptible to many secu...
