— Use of multiple paths in data gathering for wireless sensor networks balances energy dissipation among nodes in the network and maximizes network lifetime. The lifetime of such sensor system is the time when base station can receive data from all sensors in the network. A single best path puts extra load to a specific node causing lower lifetime.… (More)
— We use a genetic algorithm (GA) to create energy efficient clusters for routing in wireless sensor networks. The simulation results show that the proposed intelligent hierarchical clustering technique is more energy efficient than a few existing cluster-based routing protocols. Further, the gradual energy depletion in sensor nodes is also investigated.
— Large scale wireless sensor networks (WSNs) can be used for various pervasive and ubiquitous applications such as security, health-care, industry automation , agriculture, environment and habitat monitoring. As hierarchical clusters can reduce the energy consumption requirements for WSNs, we investigate intelligent techniques for cluster formation and… (More)
— Common applications of sensor networks include continuous monitoring where sensors are deployed over a region and the sensed data are gathered at a distant base station periodically. In each round of data gathering, our MITECRO protocol minimizes the total energy consumption of the sensor network. This may however unbalance energy consumption over all… (More)
With the advancement of micro-sensor and radio technology, wireless sensor networks are deployed in various applications. In a continuous monitoring application, sensors gather information and transmit the sensed data to base station in a periodic manner. In each data gathering round, a node generates a data packet and transmits the packet to base station,… (More)
With the current push towards using fewer antipsychotics and more non-pharmacological interventions in long-term care, it has become increasingly important for knowledge and best-practice sharing across the province. The " Good Ideas " project began in 2001 in the context of my work as a Royal Ottawa geriatric psychiatry behavioural support outreach nurse… (More)
— Within the field of Wireless Sensor Networks, one problem area is the limited energy supplies of the sensor nodes. In most situations, it is infeasible to replace the energy supply in each individual node. Thus it becomes important to minimize the energy expenditure of the sensor nodes, to get the maximum performance possible. There have been numerous… (More)
