【摘要】：無(wú)線傳感器網(wǎng)絡(luò)(Wireless Sensor Networks,WSNs)是指由一些具有感知能力、計(jì)算能力和通信能力的傳感器節(jié)點(diǎn)通過自組織形式構(gòu)成的網(wǎng)絡(luò)。由于WSNs具有部署快速、成本低,并且節(jié)點(diǎn)之間相關(guān)屬性小、適應(yīng)能力較強(qiáng)等特點(diǎn),因此被廣泛應(yīng)用于軍事、民用、通信等各個(gè)方面。然而,無(wú)線傳感器網(wǎng)絡(luò)仍具有其自身的局限性,即區(qū)域內(nèi)傳感器節(jié)點(diǎn)往往能量有限且不可蓄電,因此如何減少節(jié)點(diǎn)在傳輸數(shù)據(jù)過程中消耗的能量,提高能量的使用效率,延長(zhǎng)網(wǎng)絡(luò)的使用壽命是當(dāng)前無(wú)線傳感器網(wǎng)絡(luò)研究的熱點(diǎn)。首先,本文針對(duì)經(jīng)典鏈?zhǔn)铰酚蓞f(xié)議PEGASIS的不足進(jìn)行了改進(jìn),提出了基于節(jié)點(diǎn)密度的鏈?zhǔn)铰酚蓞f(xié)議MADD。原有的鏈?zhǔn)铰酚蓞f(xié)議在成鏈過程中一般采用貪婪算法,這種建鏈方式雖然在很大程度上縮短了通信節(jié)點(diǎn)間的距離,減少了傳輸?shù)哪芰肯?但這種成鏈方式形成的鏈路為單鏈結(jié)構(gòu),且在建鏈過程中會(huì)造成某些節(jié)點(diǎn)間不可避免的產(chǎn)生長(zhǎng)鏈。本文提出的MADD路由協(xié)議將單鏈結(jié)構(gòu)轉(zhuǎn)變?yōu)槎噫溄Y(jié)構(gòu),在使用貪婪算法建鏈的過程中,同時(shí)考慮節(jié)點(diǎn)密度與鏈上節(jié)點(diǎn)間的平均距離,減少長(zhǎng)鏈產(chǎn)生的同時(shí)避免了數(shù)據(jù)的過度集中,降低了節(jié)點(diǎn)的傳輸能耗。實(shí)驗(yàn)結(jié)果表明,該算法對(duì)于減少傳輸能耗效果明顯,有效的延長(zhǎng)了網(wǎng)絡(luò)的生命周期。其次,在MADD路由協(xié)議的基礎(chǔ)上提出了改進(jìn)算法,在鏈?zhǔn)走x取過程中,以節(jié)點(diǎn)剩余能量和與基站間的距離作為衡量標(biāo)準(zhǔn),進(jìn)而選取出適當(dāng)?shù)墓?jié)點(diǎn)充當(dāng)鏈?zhǔn)?同時(shí)根據(jù)鏈?zhǔn)坠?jié)點(diǎn)的選舉情況動(dòng)態(tài)調(diào)整主鏈,達(dá)到均衡各個(gè)鏈路節(jié)點(diǎn)的剩余能量的效果,進(jìn)一步改善無(wú)線傳感器網(wǎng)絡(luò)的生命周期。
[Abstract]:Wireless Sensor Networks (WSNs) refers to a network composed of sensor nodes with sensing, computing and communication capabilities through self-organizing forms. Because of its rapid deployment, low cost, and low correlation properties between nodes, the wireless sensor network (WSNs) is composed of sensor nodes with sensing, computing and communication capabilities. Because of its strong adaptability, wireless sensor networks are widely used in military, civil, communication and other fields. However, wireless sensor networks still have their own limitations, that is, sensor nodes in the region are often limited in energy and can not store electricity. Therefore, how to reduce the energy consumed by nodes in the process of transmitting data, improve the efficiency of energy use and prolong the service life of wireless sensor networks is a hot topic in the research of wireless sensor networks. In this paper, the shortcomings of classical chain routing protocol (PEGASIS) are improved, and a node density based chain routing protocol (MADD) is proposed. The original chained routing protocol usually adopts greedy algorithm in the process of chain formation. Although this kind of chain building method greatly shortens the distance between communication nodes and reduces the energy consumption of transmission, the link formed by this chain-forming mode is a single-chain structure. In the process of chain building, some nodes inevitably produce long chains. The MADD routing protocol proposed in this paper transforms the single-chain structure into the multi-chain structure, and in the process of using greedy algorithm to build the chain, At the same time, considering the average distance between the node density and the node on the chain, it reduces the generation of long chain and avoids the excessive concentration of data, and reduces the transmission energy consumption of the node. The experimental results show that the algorithm has obvious effect on reducing the transmission energy consumption. Secondly, based on the MADD routing protocol, an improved algorithm is proposed, which takes the residual energy of the node and the distance between the base station and the node as the measurement standard. At the same time, the main chain is dynamically adjusted according to the election situation of the chain head node to achieve the effect of balancing the residual energy of each link node, and further improve the life cycle of wireless sensor network.
