摘要

Sensor nodes are deployed over sensing fields for the purpose of monitoring certainudphenomena of interest. The sensor nodes perform specific measurements, process theudsensed data, and send the data to a base station over a wireless channel. The base stationudcollects data from the sensor nodes, analyses this data, and reports it to the users.udWireless sensor networks are different from traditional networks, because of theudfollowing constraints. Typically, a large number of sensor nodes need to be randomlyuddeployed and, in most cases, they are deployed in unreachable environments; however,udthe sensor nodes may fail, and they are subject to power constraints.udEnergy is one of the most important design constraints of wireless sensor networks.udEnergy consumption, in a sensor node, occurs due to many factors, such as: sensing theudenvironment, transmitting and receiving data, processing data, and communicationudoverheads. Since the sensor nodes behave as router nodes for data propagation, of theudother sensor nodes to the base station, network connectivity decreases gradually. Thisudmay result in disconnected sub networks of sensor nodes. In order to prolong theudnetwork¿s lifetime, energy efficient protocols should be designed for the characteristicsudof the wireless sensor network. Sensor nodes in different regions of the sensing field canudcollaborate to aggregate the data that they gathered.udData aggregation is defined as the process of aggregating the data from sensor nodes toudreduce redundant transmissions. It reduces a large amount of the data traffic on theudnetwork, it requires less energy, and it avoids information overheads by not sending alludof the unprocessed data throughout the sensor network. Grouping sensor nodes intoudclusters is useful because it reduces the energy consumption. The clustering techniqueudcan be used to perform data aggregation. The clustering procedure involves the selectionudof cluster heads in each of the cluster, in order to coordinate the member nodes. Theudcluster head is responsible for: gathering the sensed data from its cluster¿s nodes,udaggregating the data, and then sending the aggregated data to the base station.udAn adaptive clustering protocol was introduced to select the heads in the wireless sensorudnetwork. The proposed clustering protocol will dynamically change the cluster heads toudobtain the best possible performance, based on the remaining energy level of sensorudnodes and the average energy of clusters. The OMNET simulator will be used to presentudthe design and implementation of the adaptive clustering protocol and then to evaluateudit.udThis research has conducted extensive simulation experiments, in order to fully studyudand analyse the proposed energy efficient clustering protocol. It is necessary for all ofudthe sensor nodes to remain alive for as long as possible, since network quality decreasesudas soon as a set of sensor nodes die. The goal of the energy efficient clustering protocoludis to increase the lifetime and stability period of the sensor network.udThis research also introduces a new bidirectional data gathering protocol. This protocoludaims to form a bidirectional ring structure among the sensor nodes, within the cluster, inudorder to reduce the overall energy consumption and enhance the network¿s lifetime. A bidirectional data gathering protocol uses a source node to transmit data to the baseudstation, via one or more multiple intermediate cluster heads. It sends data throughudenergy efficient paths to ensure the total energy, needed to route the data, is kept to audminimum. Performance results reveal that the proposed protocol is better in terms of: itsudnetwork lifetime, energy dissipation, and communication overheads.
