Cognitive radio ad hoc networks (CRAHNs) are a class of cognitive radio networks. In recent years, they have gained popularity, and routing protocols have been proposed. Above all, the protocols based on on-demand routing are considered favorable in the literature. It is mainly because the accomplishments of ad hoc on-demand distance vector (AODV) routing and dynamic source routing (DSR) in mob...

Wireless sensor network (WSN) is an emerging technology for exchanging data in various real-time monitoring systems. The WSN has distributed nature and dynamic topology which introduces very special requirements in routing the data. Various protocols developed for routing in WSNs are broadly classified in to four categories i.e. based on Network Structure, Communication Model, Topology and Reli...

-The purpose of this research is to study and analyze various congestion control mechanisms using a number of routing protocols in Mobile Adhoc Network (MANET). As MANET is infrastructureless network so node movement and data load traffic which exceeds the network capacity, can not be predicted which leads to problem of congestion. The objective of this paper is to design a comparative analysis...

Most of the routing protocols proposed for ad-hoc networks and sensor networks are not designed with security as a goal. Hence, many routing protocols are vulnerable to an attack by an adversary who can disrupt the network or harness valuable information from the network. Routing Protocols for wireless sensor networks are classified into three types depending on their network structure as Flat ...
