An Energy Aware Geocast Algorithm Using 2-hop Neighbour Knowledge in Sensor Networks
نویسندگان
چکیده
Geocast is a mechanism which sends a packet to all the sensor nodes in a certain geographic area. It enables one to collect information from the designated area within a sensor network. Because sensor nodes are operating with limited power source and sending/receiving packets are most energy consuming operations for sensor networks, geocast algorithms should be energy efficient. In this paper we introduce a new geocast protocol which minimizes energy usage and overhead by utilizing the knowledge on the neighbours and their energy levels. We evaluate the performance of the proposed protocol with simulation.

This paper proposes an energy-efficient geocast algorithm for wireless sensor networks with guaranteed delivery of packets from the sink to all nodes located in several geocast regions. Our approach is different from those existing in the literature. We first propose a hybrid clustering scheme: in the first phase we partition the network in cliques using an existing energy-efficient clustering ...

Mobile sensor networks rely heavily on inter-sensor connectivity for collection of data. Nodes in these networks monitor different regions of an area of interest and collectively present a global overview of some monitored activities or phenomena. A failure of a sensor leads to loss of connectivity and may cause partitioning of the network into disjoint segments. A number of approaches have be...

LEACH is the most popular clastering algorithm in Wireless Sensor Networks (WSNs). However, it has two main drawbacks, including random selection of cluster heads, and direct communication of cluster heads with the sink. This paper aims to introduce a new centralized cluster-based routing protocol named LEACH-AEC (LEACH with Adaptive Energy Consumption), which guarantees to generate balanced cl...

Energy consumption is considered as a critical issue in wireless sensor networks (WSNs). Batteries of sensor nodes have limited power supply which in turn limits services and applications that can be supported by them. An efcient solution to improve energy consumption and even trafc in WSNs is Data Aggregation (DA) that can reduce the number of transmissions. Two main challenges for DA are: (i)...
