【Abstract】 Recent advancement in electronics and wireless communications has enabled the development of sensor networks,which perform distributed sensing task and can be used for various application areas. Traditional routing protocols can not be used for sensor networks because conventional protocols focus on providing high quality of service and not on limited energy supply. This paper makes a survey of recent works on routing mechanism for sensor networks. First the paper presents the characteristics of sensor networks. Then it classifies the main routing protocols proposed in the literature .describes and analyzes them in detail.更多还原
