A characteristic feature of ad hoc networks is the infrastructure less and seamless connectivity of the wireless mobile nodes. Mobility plays an important role in the connectivity of these nodes. In this paper a performance comparison of five important mobility models; Community Model, Group Force Mobility Model (GFMM), Reference Point Group Mobility(More)
A sensor network is a system that consists of thousands of very small stations called sensor nodes. The communication among nodes is done in a wireless fashion, and thus, the name of wireless sensor networks. Wireless sensor networks (WSN) have generated tremendous interest among researchers in recent years because of their potential usage in wide variety(More)
In this paper the focus is on the performance study of four routing protocols, namely AODV, AODVUU, RAODV and AOMDV. We call these protocols AODV family of protocols as all these protocols consider AODV as the base routing protocol upon which these protocols are improved. Even though AODV and AODVUU are not different protocols, we wanted to see if there is(More)
The increasing demands and requirements for wireless communication systems especially in settings where access to wired infrastructure is not possible like natural disasters, conferences and military settings have led to the need for a better understanding of fundamental issues in TCP optimization in MANETS.TCP primarily designed for wired networks, faces(More)
Reactive routing protocols like AODV and DSR uses Expanding ring search algorithm for route discovery in MANET. This paper presents enhancement in basic TTL sequence based ERS. This results into faster route discovery, lesser routing traffic and efficient energy operation in MANET. We have considered circular network area with equal node density in entire(More)
The integration of Internet and ad hoc mobile network exhibit differences in their network architecture. Thus, the interconnection is achieved by using Internet gateways, which acts as bridges between MANET and Internet. When a node in ad hoc network wants to access Internet, it has to first find route to a gateway. Therefore an efficient gateway discovery(More)
Wireless sensor networks have a broad variation of applications within the surveillance, military, atmosphere monitoring and medical fields. Coverage and connectivity of sensor networks demonstrates how well a region is monitored. The coverage issues have been studied extensively. Particularly the coverage with respect to connectivity and network lifetime(More)
In mobile ad hoc networks, the movement of the mobile nodes is one of the important characteristics because it can affect the performance of the routing protocol. The mobility pattern directly influences when communication links between nodes are established or broken, which is associated with the network topology. In this paper, the impact of the different(More)
