Public utilities such as water, electricity and gas are essential services that play a vital role in economic and social development. Automation of public utility services addresses the huge losses faced by the utility services today, due to non-accounting of distributed utility resources. Automation improves government revenues. The different type of architectures are proposed and designed for automated...
Wireless Sensor Networks(WSN) are vulnerable to many types of hackers who might get into the network with the intent of fetching its significant data and destroying the network. The sink node in WSN that maintains the database of entire network is also prone to security violations and there is no such security mechanism devised for communicating the data to other nodes. Hence, there is a need to design...
Key dependent block cipher algorithms have been designed and implemented by researchers. However, the performance in terms of security, speed and synchronisation for modern communication has not been sufficiently addressed and analysed. In this paper, we propose novel family of 128-bit Substitution-Permutation Network (SPN) block cipher encryption algorithms which simultaneously uses key based S-box,...
In this paper, we propose a novel idea of an active node model in Wireless Sensor Network (WSN) to identify the faulty nodes using battery power model and interference model. Fault tolerance against low battery power is designed through hand-off mechanism where in the faulty node selects the neighboring node having highest power and transfers all the services that are to be performed by the faulty...
Routing in mobile ad hoc networks (MANETs) for groups should aim at providing reliable and robust multicast routes to the group members against link failures, node failures and mobility conditions. The authors propose an agent-based multicast routing scheme in MANET that builds a backbone in the form of a reliable ring and finds multicast routes. The authors use the convex hull algorithm to find the...
The floorplan decides the optimum layout of individual components in VLSI design process and it needs intelligence to be in-built in the process. It allows knowledge of design process to be abstracted and grouped to form domains, which are distinct entities providing specialized design services. It allows VLSI design processes to be realized by integrating a set of domain that offers integrated design...
