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)
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 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)
This paper investigates and undertakes simulation based study of Adhoc routing protocols in Wireless Sensor Networks. For our simulation based study we have considered three different scenarios where a Adhoc routing protocol can be applied, namely a) Phenom nodes with Mobility, Sensor nodes with mobility while the SINK node is stationary b) Phenom nodes(More)
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)
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)
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, we successfully demonstrate the role of Bluetooth Low Energy (BLE) in automating the Proximity based solutions for Internet of Things (IoT) by considering a real world use case scenario. Devices in IoT must be low powered in order to extend their lifetime. BLE compatible AltBeacon is aptly suited for this purpose. We have developed an(More)
