Wireless sensor networks (WSNs) have gained a lot of attention in both public and research communities. One issue in wireless sensor networks is achieving efficient operation because of the limited available power. Many Heuristics were designed to enhance power reservoir of sensors and maximize their life time. Online Maximum Lifetime heuristics (OML) and(More)
Modelling business processes using BPMN has been emerging as the preferred choice for organisations seeking to enact their business processes in service-oriented environments. However, a number of organisations have their business processes modelled using Role Activity Diagramming, RAD. In this research, we introduce a new approach to translating RAD(More)
Leader election algorithms solve the instability problem in the network which is caused by leader failure .In this paper, we propose a new leader election algorithm in two dimensional torus networks. The algorithm aims to elect one node to be a new leader. The new leader is identified by some characteristics not in the other nodes in the network. When the(More)
—Biometric based cryptography system provides an efficient and secure data transmission as compare to the traditional encryption system. However, it is a computationally challenge task to solve the issues to incorporate biometric and cryptography. In connection with our previous works, this paper reveals a robust cryptosystem using iris biometric pattern as(More)
