Wireless sensor networks have been widely used in many applications such as military monitoring, target tracking and surveillance. Security issue is need to more concern. Routing protocol is the core technology of the network layer in wireless sensor networks. Many attackers disrupt the network with routing attack, which will do serious damage to wireless sensor networks. Consider the scare ene...

Wireless Sensor Networks are extremely vulnerable to any kind of routing attacks due to several factors such as wireless transmission and resource-constrained nodes. In this respect, securing the packets is of great importance when designing the infrastructure and protocols of sensor networks. This paper describes the hardware architecture of secure routing for wireless sensor networks. The rou...

Security is an essential requirement in mobile ad hoc networks to provide protected communication between mobile nodes. MANETs are vulnerable to various attacks; black hole is one of the possible attacks. Black hole is a type of routing attack where a malicious node advertise itself as having the shortest path to all nodes in the environment by sending fake route reply. We attempt to focus on a...

Mobile ad-hoc network abbreviated as MANET is most emerging and highly demanding wireless network technology. Due to the property of self-deliberate, where all point of network behaves like source or router and also all nodes are keeps on moving freely in network area. Mobile ad hoc network perform important role in connectionless environment. Security is the most fundamental requirement in mob...

AODV (Ad hoc On Demand Vector) is a reactive routing protocol in wireless mobile ad hoc network (MANET). AODV is accepted because of its capacity to adjust quickly in dynamic system environment with least overhead and small management packet size. The adhoc networks are all that much helpless against Dos attacks on the network layer. Blackhole and Grayhole attacks are the far reaching attacks o...

AbstactA freely roaming nodes forming as a group of network for effective communication is called Mobile Ad hoc Networks (MANET). In MANET nodes have the liberty of moving around the network with no defensive boundaries and often nodes join and leave the network as per their need due to this nature MANET’s are insecure. In this insecure environment Routing is a critical aspect which must be don...

Wireless Mesh Network (WMN) has emerged as a key technology and found a great deal of interest for the researchers in the recent past. Hybrid Wireless Mesh Protocol (HWMP) is the default path selection (i.e., routing) protocol fully specified in the current draft D.1.06 of 802.11s for WMN. However, security in routing or forwarding functionality is not specified in the standard. As a consequenc...

Distributed denial-of-service (DDoS) attacks are network-wide attacks that cannot be detected or stopped easily. They affect “natural” spatiotemporal packet traffic patterns, i.e. “natural distributions” of packets passing through the routers. Thus, they affect “natural” information entropy profiles, a sort of “fingerprints”, of normal packet traffic. We study if by monitoring information entro...

Mobile Ad-Hoc networks are self-configuring and self-organizing multi-hop wireless networks. They do not have any fixed infrastructure or centralized management. Due to this, the ad hoc networks are vulnerable to attacks. The routing protocol for MANET considered in this paper is AODV(Ad hoc On-demand Distance Vector Routing Protocol). Blackhole and Wormhole nodes are malicious nodes which degr...

The role of infrastructure-less mobile ad hoc networks (MANETs) in ubiquitous networks is outlined. In a MANET there are no dedicated routers and all network nodes must contribute to routing. Classification of routing protocols for MANET is based on how routing information is acquired and maintained by mobile nodes and/or on roles of network nodes in a routing. According to the first classifica...
