Wireless sensor networks are made up of many inexpensive nodes geographically distributed over a certain area where the sensor node components include sensors, actuators, processing unit and storage, location tracking and power supply unit. These types of networks have large range of applications that include environmental pollution, vehicle and building safety etc. In sensor networks, the nodes are...
Due to open network nature of wireless sensor networks make them highly vulnerable to a variety of security attacks and easy target for adversaries, which may capture these nodes, analyze and easily insert fake route information. Wireless sensor network is an emerging, cost effective and unsupervised solution for collecting this information from the physical world and sending this information back...
A MANET is a infrastructure-less and auto configurable network of mobile nodes which are connected without wires. As per proposal of this paper, the communication in a MANET works on set of random keys called KEY1=X+KEY0, KEY2=X+KEY1, KEY3=X+KEY2…KEYN=X+KEYN−1 to establish the connection between nodes and applies to validate the packets. Since there could be a issue of keys length, hence we can enforce...
In this paper we present a distributed self organizing trust based clustering framework for securing ad hoc networks. The mobile nodes are vulnerable to security attacks, so ensuring the security of the network is essential. To enhance security, it is important to evaluate the trustworthiness of nodes without depending on central authorities. In our proposal the evidence of trustworthiness is captured...
This paper presents a QoS research study on ad hoc sensor networks from a delay point of view when WEP (wired equivalent privacy) security is enabled or disabled. A queuing model with one queue and two servers is used to estimate the security delays in the traffic between ad hoc sensor nodes. An algorithm is designed to estimate the service time delay and the security time delay based on measured...
