“…Moreover, due to this limit, this paper only gives an analytical simulation result. Some simulators like NS and OPNET are well-established and have been applied for these specific WSN communication technologies [30,31,32,33], such as Zigbee, WiFi, LTE and so on. By choosing a WSN communication technology, we can extend the simulation work on these well-established simulators to verify more indicators.…”

On-Road Sensor Networks (ORSNs) play an important role in capturing traffic flow data for predicting short-term traffic patterns, driving assistance and self-driving vehicles. However, this kind of network is prone to large-scale communication failure if a few sensors physically fail. In this paper, to ensure that the network works normally, an effective fault-tolerance mechanism for ORSNs which mainly consists of backup on-road sensor deployment, redundant cluster head deployment and an adaptive failure detection and recovery method is proposed. Firstly, based on the N − x principle and the sensors’ failure rate, this paper formulates the backup sensor deployment problem in the form of a two-objective optimization, which explains the trade-off between the cost and fault resumption. In consideration of improving the network resilience further, this paper introduces a redundant cluster head deployment model according to the coverage constraint. Then a common solving method combining integer-continuing and sequential quadratic programming is explored to determine the optimal location of these two deployment problems. Moreover, an Adaptive Detection and Resume (ADR) protocol is deigned to recover the system communication through route and cluster adjustment if there is a backup on-road sensor mismatch. The final experiments show that our proposed mechanism can achieve an average 90% recovery rate and reduce the average number of failed sensors at most by 35.7%.

Jaringan monitoring penggunaan energi listrik yang dikembangkan Politeknik Negeri Samarinda (Polnes) telah dipasang di lima gedung dalam kampus Polnes sejak tahun 2020 dan menjalani running test selama hampir dua tahun. Walaupun hampir tidak pernah menjalani perawatan, sistem ini secara umum bekerja dengan baik dan hanya mengalami penggantian satu unit mikrokontroler. Walaupun demikian, kemampuan sistem ini perlu terus ditingkatkan antara lain dengan mengubah pola komunikasi yang awalnya searah menjadi dua arah. Pengubahan pola ini akan meningkatkan kemampuan jaringan karena operator tidak hanya bisa mendapatkan data yang dikirim secara regular oleh unit-unit sensor node (SN) tetapi juga mampu mengatur data apa yang diinginkan, bahkan mampu mengatur aktuator yang diletakkan pada SN. Metode yang dilakukan pada penelitian ini meliputi modifikasi mekanisme protokol komunikasi, modifikasi paket data, pemrograman gateway dan SN, dilanjutkan dengan pengujian, dan analisa hasilnya. Hasil pengujian menunjukkan bahwa sembilan jenis perintah dengan tiga inisiator yang berbeda telah menghasilkan mekanisme yang sesuai dengan perencanaan.

“…Complex structured WSNs use a multi-hop network structure as a connection method. In such networks, as shown in Figure 1, the sensor nodes extend coverage of the network by communicating with each other [4], [5]. In multi-hop networks, the sensor nodes perform not only their own sensing tasks but also for its neighbor nodes the relay function.…”
