Wireless Sensor technology is one among the fast emerging technologies in the current scenario and it has wide range of application also which has small sensors with minimum communicational and computational power. Depending on the overhead of a node, the energy consumption varies with each other. This leads to the non-uniform distribution of the energy which in turn degrades the performance of the...
The technology based ubiquitous patient monitoring is regarded as a viable solution for managing the chronic diseases and medical emergencies in order to economize the healthcare services. The reliability of end to end communication between patients and healthcare services in wireless patient monitoring is the critical requirement in such systems irrespective of time and location dependencies. In...
WSNs are gradually penetrating all spheres of security, industry and civil sectors. Since the very inception of the concept, a need for enhancing energy efficiency and longevity of the networks is felt. Routing protocols designed for WSNs have evolved over the years in order to serve this purpose better. This paper summarizes the concerns of a WSN and discusses how these were addressed through innovations...
A MANET is a infrastructure-less and auto configurable network of mobile nodes which are connected without wires. As per proposal of this paper, the communication in a MANET works on set of random keys called KEY1=X+KEY0, KEY2=X+KEY1, KEY3=X+KEY2…KEYN=X+KEYN−1 to establish the connection between nodes and applies to validate the packets. Since there could be a issue of keys length, hence we can enforce...
Mobile ad hoc network requires lots of attention towards secure reputed routing. This paper proposed a novel reputed e-ARAN scheme to detect and handle authenticated selfish nodes, based on reputed OCEAN scheme. With description of all four phases of reputed e-ARAN it also proves that the proposed scheme gives better end-to-end delay and throughput as compare to existing ARAN protocol.
Security is a key aspect in networks that circulate critical information. Vehicular Ad Hoc Network (VANET) is one such network where vehicles transmit and receive traffic information and emergency alerts. It is imperative to ensure only legitimate nodes join the network, since VANET thrives on authentic and accurate information. This paper proposes a vehicle authentication scheme based on weak encryption...
Vehicular ad hoc networks (VANETs) are receiving enormous research attention in the wake of rising challenges of safe driving, and demand for infotainment services on the move. Information security in VANETs is a critical design issue, since public lives could be at stake. This paper presents a novel sender authentication scheme for enhancing VANET security. The scheme makes use of hash chaining,...
We analyze the uplink outage probability at the randomly, but not necessarily independently nor homogeneously, distributed cellular network receivers caused by an overlaid secondary ad hoc network. Unlike the previous works that assumed exact circular exclusion regions (or guard zones), we incorporate a sensing mechanism to decrease the significant effect of the nearby interferers. We consider Rayleigh-faded...
