【摘要】：近年來,隨著傳感器技術(shù)、無線通信技術(shù)、分布式信息處理技術(shù)、微電子技術(shù)和嵌入式系統(tǒng)技術(shù)等相關(guān)技術(shù)領(lǐng)域的不斷發(fā)展,無線傳感器網(wǎng)絡(luò)(Wireless Sensor Networks,WSNs)已被廣泛應(yīng)用于智能交通管理、農(nóng)業(yè)管理、軍事系統(tǒng)、智能家居、工業(yè)控制、環(huán)境保護、醫(yī)療衛(wèi)生等領(lǐng)域,并被稱為21世紀應(yīng)用最廣的技術(shù)之一。與以往傳統(tǒng)網(wǎng)絡(luò)相比,WSNs具有自組織性、網(wǎng)絡(luò)拓撲動態(tài)性、網(wǎng)絡(luò)規(guī)模大、以數(shù)據(jù)為中心等特點；同時傳感器節(jié)點受自身硬件條件的限制,如存儲能力不足、能量有限和計算能力弱等,這些均給無線傳感器網(wǎng)絡(luò)路由算法的設(shè)計帶來了一定難度。 無線傳感器網(wǎng)絡(luò)路由算法根據(jù)路由選擇的不同,通�？煞譃榛谀芰扛兄穆酚伤惴ā⒒诓樵兊穆酚伤惴�、基于地理位置信息的路由算法和基于可靠性的路由算法。在設(shè)計時通常按照不同的應(yīng)用環(huán)境和設(shè)計要求,選擇最合適的路由協(xié)議來組建網(wǎng)絡(luò)。相比其他的路由算法,基于地理位置信息的WSNs路由通過定位方法獲取節(jié)點位置信息來傳遞消息包,從而無需消耗額外的能量和存儲空間去建立和維護路由鏈表,對傳感器節(jié)點的存儲能力、能量和計算能力的要求相對較低,其通常在某些環(huán)境中更加符合WSNs路由的設(shè)計要求。 針對無線傳感器網(wǎng)絡(luò)中因空洞引起的路由效率降低問題,該文提出了基于三維胞元空間的能量高效性多通道協(xié)助路由算法(3D-EEMCR)。該算法根據(jù)能量損耗模型,權(quán)衡考慮節(jié)點的剩余能量和位置信息來選舉胞父節(jié)點,以平衡網(wǎng)絡(luò)能耗；并采用主通道和輔助通道相互協(xié)助的周邊路由模式完成空洞區(qū)域的路由。仿真結(jié)果表明,3D-EEMCR相比3D-GPR和3D-CSR能夠有效提高消息包的發(fā)送率,降低網(wǎng)絡(luò)的平均能耗,延長網(wǎng)絡(luò)的生存周期。
[Abstract]:In recent years, with the development of sensor technology, wireless communication technology, distributed information processing technology, microelectronics technology and embedded system technology, Wireless Sensor Networks (WSNs) has been widely used in the fields of intelligent transportation management, agricultural management, military systems, smart home, industrial control, environmental protection, medical and health, etc. Compared with the traditional network, WSNs have the characteristics of self-organization, dynamic network topology, large network scale and data center, and the sensor nodes are restricted by their own hardware conditions. Such as insufficient storage capacity, limited energy and weak computing power, all of these bring some difficulties to the design of routing algorithm in wireless sensor networks. The routing algorithms of wireless sensor networks can be divided into energy-aware routing algorithms and query-based routing algorithms according to the different routing choices. The routing algorithm based on geographical location information and the routing algorithm based on reliability usually choose the most suitable routing protocol to build the network according to different application environments and design requirements. Compared with other routing algorithms, The WSNs routing based on geographical location information acquires the node location information to transmit the message packet, so it does not need to consume extra energy and storage space to build and maintain the routing chain list, and the storage capacity of the sensor node. The requirements of energy and computing power are relatively low, and it is usually more suitable for the design of WSNs routing in some environments. In order to reduce the routing efficiency caused by voids in wireless sensor networks, an energy efficient multi-channel assisted routing algorithm (3D-EEMCRA) based on three-dimensional cellular space is proposed in this paper, which is based on the energy loss model. Considering the residual energy and location information of the nodes to select the parent nodes to balance the network energy consumption; The simulation results show that compared with 3D-GPR and 3D-CSR, 3D-GPR and 3D-CSR can effectively improve the sending rate of message packets and reduce the average energy consumption of the network. Extend the lifetime of the network.
