【摘要】：由于移動自組織網(wǎng)絡中節(jié)點的電量有限,節(jié)點會隨著電量消盡而退出網(wǎng)絡,從而影響網(wǎng)絡的性能,因此延長節(jié)點壽命成為移動自組織網(wǎng)節(jié)能研究的熱點�，F(xiàn)有節(jié)能研究主要集中在解決傳輸一個分組總電量消耗最小化和網(wǎng)絡壽命最大化的節(jié)點耗電均衡問題。但是,只追求總電量消耗最少的路由評價方式往往會導致耗電量較低節(jié)點負載過重,且總耗電最小并未從節(jié)點的角度節(jié)省電量;只追求均衡節(jié)點耗電量會造成節(jié)點電量的浪費;少數(shù)協(xié)議單純的將絕對最小化耗電總量與均衡耗電相結(jié)合,但都是從全局的角度而未從局部角度為延長節(jié)點壽命發(fā)揮節(jié)點自身的節(jié)能自主性。面向節(jié)點發(fā)射功率固定的網(wǎng)絡,本文提出一種基于節(jié)點電池放電特性節(jié)能的路由協(xié)議RBAODV,該協(xié)議根據(jù)電池放電特性將電池剩余電量劃分為3個不同等級,進而采取各自相應的評估策略,使高剩余電量節(jié)點積極參與到協(xié)助轉(zhuǎn)發(fā)分組中來而提高路由評價值,而低剩余電量節(jié)點則為保護自身電量降低路由評價值,路由選擇時通過綜合考慮跳數(shù)和路徑上各節(jié)點剩余電量評價值來決定路由。實驗結(jié)果顯示,與AODV協(xié)議性能相比,RBAODV協(xié)議能有效避免剩余電量過低節(jié)點,從而延長網(wǎng)絡壽命。面向節(jié)點發(fā)射功率可調(diào)的網(wǎng)絡,基于節(jié)點轉(zhuǎn)發(fā)一個數(shù)據(jù)分組耗電量最小的角度,由于現(xiàn)有節(jié)能協(xié)議在網(wǎng)絡節(jié)點轉(zhuǎn)發(fā)路由控制分組時并沒有考慮節(jié)點剩余電量。本文提出一種改進方案RBTBPR協(xié)議,即在中間節(jié)點轉(zhuǎn)發(fā)路由請求包時優(yōu)先考慮該路由請求包所經(jīng)路徑的剩余壽命較多;其次考慮上一跳節(jié)點轉(zhuǎn)發(fā)該路由請求包耗電最少;再考慮該請求包所經(jīng)路徑的累積耗電總量最少;最后考慮該請求包所經(jīng)路徑的跳數(shù)最少。該協(xié)議并對節(jié)點在當前剩余電量值下剩余壽命的估算方法進行了改進,提出只關(guān)注節(jié)點當前剩余電量與節(jié)點已運行的時間,即節(jié)點剩余壽命為當前剩余電量除以已消耗電量與已運行時間的比值。實驗結(jié)果顯示,與TBPR協(xié)議、MCPR協(xié)議相比,RBTBPR協(xié)議能延長節(jié)點的網(wǎng)絡壽命。
[Abstract]:Due to the limited power of nodes in mobile ad hoc networks, the nodes will withdraw from the network with the loss of electricity, thus affecting the performance of the network. Therefore, prolonging the lifetime of nodes has become a hot topic in the research of energy conservation in mobile ad hoc networks. The existing energy conservation research focuses on solving the problem of node power equalization in which the total power consumption of a packet is minimized and the network lifetime is maximized. However, the route evaluation method which only pursues the least consumption of total electricity consumption often leads to the low power consumption of nodes, and the minimum total power consumption does not save the power from the point of view of the nodes, and the pursuit of balancing the power consumption of the nodes will lead to the waste of the power consumption of the nodes. A few protocols simply combine absolute minimization of total power consumption with balanced power consumption, but all of them are from a global point of view, but not from a local point of view to extend node life to give full play to the node's own energy saving autonomy. In this paper, a routing protocol RBAODV, which is based on node battery discharge characteristics and energy saving, is proposed for networks with fixed node-emitting power. According to the characteristics of battery discharge, the residual battery power is divided into three different classes. Then the corresponding evaluation strategies are adopted to make the high residual electricity nodes actively participate in the assisted forwarding packets to improve the routing evaluation value, while the low residual electricity level node reduces the routing evaluation value to protect its own power. Routing is determined by considering the number of hops and the evaluation value of the residual power of each node in the route. The experimental results show that compared with the performance of AODV protocol, the RBAODV protocol can effectively avoid the low residual power and prolong the network life. Based on the minimum power consumption of a data packet transmitted by a node, the existing energy saving protocols do not consider the residual power of the node when forwarding the routing control packet to the network node. In this paper, an improved RBTBPR protocol is proposed, in which priority is given to the remaining lifetime of the routing request packet when the intermediate node forwards the routing request packet, and the last hop node transmits the routing request packet with the least power consumption. Then consider that the total cumulative power consumption of the request packet is the least, and the number of hops of the request packet is the least. The protocol also improves the method of estimating the residual life of the node under the current residual electricity value, and proposes to focus only on the current residual power of the node and the running time of the node. That is, the residual life of the node is the ratio of the current residual power divided by the consumed power to the running time. Experimental results show that RBTBPR protocol can prolong the network lifetime of nodes compared with TBPR protocol and MCPR protocol.
