Study of Routing Protocols in Telecommunication Networks

In this paper we have discussed the problem of routing in telecommunication networks and the salient characteristics of some of the most popular routing schemes. In particular, we have discussed the characteristics of adaptive and multipath routing solutions versus static and single-path strategies

Study and Analysis of Ant System

Alot of species of ants have a trail-laying/trailfollowing behavior when foraging. While moving, individual ants deposit on the ground a volatile chemical substance called pheromone, forming in this way pheromone trails. Ants can smell pheromone and, when choosing their way, they tend to choose, in probability, the paths marked by stronger pheromone concentrations. In this way they create a sort of attractive potential field, the pheromone trails allows the ants to find their way back to food sources (or to the nest). Also, they can be used by other ants to find the location of the food sources discovered by their nest mates

An Architectural Metrics Scorecard Based Approach to Intrusion Detection System Evaluation for Wireless Network

Wireless IDS architectural metrics are used to compare the intended scope, architecture of wireless IDS, and how they match the deployment architecture. These metrics can be used to evaluate the architectural efficiency of a wireless IDS and can help in designing efficient wireless IDS. Wireless IDS analyze wireless specific traffic including scanning for external users trying to connect to the network through access points and play important role in security to wireless network. Design of wireless IDS is a difficult task as wireless technology is advancing every day, Architectural metrics can play an important role in the design of wireless IDS by measuring the areas concern with the architecture of a wireless IDS. In this paper we describe a set of architectural metrics that are relevant to wireless IDS. A 201C;scorecard201D; containing the set of values is used as the centerpiece of testing and evaluating a wireless IDS. Evaluation of a wireless IDS can be done by assigning score to various architectural metrics concern with wireless IDS. We apply our architectural metrics scorecard based evaluation approach to three popular wireless IDS Snort-wireless, AirDefense Guard, and Kismet. Finally we discuss the results and the opportunities for further work in this area

A Performance Metrics Scorecard Based Approach to Intrusion Detection System Evaluation for Wireless Network

Wireless Intrusion Detection System (IDS) performance metrics are used to measure the ability of a wireless IDS to perform a particular task and to fit within the performance constraints. These metrics measure and evaluate the parameters that impact the performance of a wireless IDS. Wireless IDS analyze wireless specific traffic including scanning for external users trying to connect to the network through access points and play important role in security to the wireless network. Design of wireless IDS is a difficult task as wireless technology is advancing every day, performance metrics can play an important role in the design of efficient wireless IDS by measuring the factors concern with the performance of a wireless IDS. In this paper we provide a performance metrics scorecard based approach to evaluate intrusion detection systems that are currently popular for wireless networks in the commercial sector. We provide a set of performance metrics that are relevant to wireless IDS and use a 201C;scorecard201D; containing the set of values as the centerpiece of testing and evaluating a wireless IDS. Evaluation of a wireless IDS is done by assigning score to various performance metrics concern with wireless IDS. We apply our performance metrics scorecard evaluation based approach to three popular wireless IDS Snort-wireless, AirDefense Guard, and Kismet.

Securing Cluster Head Selection in Wireless Sensor Networks

Wireless Sensor network routing protocols are prone to various attacks as these protocols mainly provide the function of routing data towards the sink. LEACH is a one of the routing protocol used for clustered implementation of wireless sensor network with Received Signal Strength based dynamic selection of Cluster Heads. But, as with other routing protocols, LEACH is also prone to HELLO flood attack when the malicious sensor node becomes the Cluster Head. Cryptographic and non-cryptographic approaches to detect the presence of HELLO flood attack also exist but they lack efficiency in some way. In this paper, an efficient protocol is proposed for the detection and prevention of HELLO Flood attack in wireless sensor network. Cluster heads are vulnerable to various malicious attacks and this greatly affects the performance of the wireless sensor network. Cryptographic approaches to prevent this attack are not so helpful though some non-cryptographic methods to detect the HELLO Flood attack also exist but they are not too efficient as they result in large test packet overhead. In this paper, we propose HRSRP (Hello flood attack Resistant Secure Routing Protocol) extension to LEACH protocol so as to protect the cluster head against Hello flood attack. HRSRP is base on encryption using Armstrong number and decryption using AES algorithm to verify the identity of cluster head. The proposed technique is implemented in NS2, the experimental results clearly indicate the proposed technique has significant capability for the detection of hello flood attack launched for making the malicious node as the cluster head
