LIFETIME MAXIMIZATION OF A MOBILE WSN USING ZRP-FUZZY CLUSTERING PROTOCOL BASED ON ANT-LION OPTIMIZER

Wireless Sensor Networks require energy-efficient protocols for communication and data fusion to integrate data and extend the lifetime of the network. An efficient clustering algorithm for sensor nodes will optimize the energy efficiency of WSNs. However, the clustering process requires additional overhead, such as selection of cluster head, cluster creation, and deployment. This paper prepared a modified ZRP for mobile WSN clustering scheme and optimization using ant-lion optimization algorithm and so far named as mobility cluster head fuzzy logic based on the zone routing protocol (ZRP-FMC-ALO). Which proposed fuzzy logic approach based on three descriptors node for the selection of the CH nodes such as, residual energy, the concentration, and the centrality of the node and also exploited the concept of the mobility of the Base Station (BS) to prolong the life span of a WSN. The performance of the proposed protocol compared with the famous protocol such as LEACH. Using the MATLAB simulator and the result shows that it outperforms in terms of the WSN network lifetime, the average remaining-consuming energy, and the number of a live node.

Proposed emerged and enhanced routing protocols for wireless networks

The problem motivation of this work deals with how to control the network overhead and reduce the network latency that may cause many unwanted loops resulting from using standard routing. This work proposes three different wireless routing protocols which they are originally using some advantages for famous wireless ad-hoc routing protocols such as dynamic source routing (DSR), optimized link state routing (OLSR), destination sequenced distance vector (DSDV) and zone routing protocol (ZRP). The first proposed routing protocol is presented an enhanced destination sequenced distance vector (E-DSDV) routing protocol, while the second proposed routing protocol is designed based on using the advantages of DSDV and ZRP and we named it as DS-ZRP routing protocol. The third proposed routing protocol is designed based on using the advantaged of multipoint relays in OSLR protocol with the advantages of route cashing in DSR protocol, and we named it as OLS-DSR routing protocol. Then, some experimental tests are doing by demonstration case studies and the experimental results proved that our proposed routing protocols outperformed than current wireless routing protocols in terms of important network performance metrics such as periodical broadcast, network control overhead, bandwidth overhead, energy consumed and latency.

Pencarian Rute yang Handal Berbasis Energi Menggunakan Algoritma EA-SHORT pada Protokol Routing ZRP di Jaringan MANET

Mobile Ad-Hoc Network (MANET) adalah jaringan wireless dari kumpulan node yang tidak memiliki router tetap. Setiap node dalam jaringan bertindak sebagai router yang bertanggung jawab untuk menemukan dan menangani rute antar node. Dalam penelitian ini, konsep energy aware menggunakan algoritma EA-SHORT diterapkan pada kerangka kerja Zone Routing Protocol (ZRP). EA-SHORT mencoba mendistribusikan beban jaringan ke semua node yang ada dengan memanfaatkan variasi jumlah energi dengan memilih node yang memiliki cukup energi yang dapat berpartisipasi dalam rute dan menghindari node yang memiliki energi rendah. Kinerja ZRP akan dibandingkan dengan EA-SHORT ZRP yang telah dimodifikasi dengan EA-SHORT yang diukur dari nilai parameter yang ditentukan. Dari simulasi, hasilnya menunjukkan, pada node 50, throughput meningkat sebesar 12,374%. Untuk 100 node, peningkatan sebesar 44.597%. Pada rata-rata average end to end delay , dengan 50 node, nilai EA-SHORT ZRP menurun sebesar 20.063%, 100 node EA-SHORT ZRP menurun sebesar 8.375%. Hasil PDR pada EA-SHORT ZRP dengan 50 node meningkat 0,545%, dan untuk EA-SHORT ZRP 100 node meningkat sebesar 21,301%

Determining an optimum zone radius for zone routing protocol (ZRP) based on node mobility

Mobility is one of the important issues in Mobile Ad hoc Networks (MANET). By definition, MANET nodes are free to move around and this may cause difficulty in routing. MANET routing protocols must consider this factor when making routing decision. Zone Routing Protocol (ZRP) is a hybrid routing protocol, which utilizes the proactive and reactive routing protocols advantages. ZRP proactively maintains routing information within a routing zone, while reactively discovering routes to destinations beyond the routing zone. Since ZRP is based on the concept of routing zone, determining an optimum routing zone radius has the major impact on the performance of that protocol. In this research, we studied the effect of zone radius on the performance of ZRP with different levels of node mobility. Node mobility is defined using two different parameters: node speed and pause time. Based on the simulation results, ZRP protocol using zone radius of two provides the best packet delivery fraction, throughput and normalized routing load. However, a larger zone radius will provide a lower delay.
