Wireless Sensor Networks (WSNs) is collection of large number of sensor nodes which are of limited capabilities, to collect sensitive information. With the advancement of this technology, one of the major concerns these days is of security. There are so many attacks possible on WSN, in Distributed-Denial of Service (DDOS) attacks, malicious nodes adapts many attacks such as flooding attack, black...
Wireless sensor network is one of the developing ranges of research in present situation. A Wireless sensor network comprises of geographically dispersed self-governing tiny sensor nodes with little battery life to screen and control over the physical parameters or ecological conditions, for example, temperature, sound, pressure, humidity and so on and this data is gone by the sensor nodes in the...
A MANET is an autonomous collection of mobile users where network topology may change rapidly and unpredictably over time. In case of more number of receivers, multicasting is the appropriate mechanism. For MANETs many multicast protocols have been proposed and prominent among them are On-Demand Multicast Routing Protocol (ODMRP), Multicast Ad-hoc On-Demand Distance Vector (MAODV), Protocol Independent...
A MANET consists of self-coordinating mobile nodes which show dynamic behavior during their multicast operations. Thus, it is imperative to obtain the best way to provide multicast services in this kind of environment. For this purpose investigation and quantification of existing multicast routing protocols is the foremost step. In this article detailed discussion is done regarding basic behaviors...
MANET is an assembly of mobile nodes having the capability of configure any momentarily network without the assistance of any established infrastructure or centralized supervision. Due to the self-arrangement and self maintenance abilities, MANETs become highly vulnerable to various kinds of attacks. So, Security challenges have become a key concern to provide secure communication between mobile nodes...
