A Hybrid Energy Efficient Protocol for Mobile Ad Hoc Networks

We proposed an energy conservation technique called Location Based Topology Control with Sleep Scheduling for ad hoc networks. It uses the feature of both topology control approach and power management approach. Like the topology control approach, it attempts to reduce the transmission power of a node, which is determined from its neighborhood location information. A node goes to sleep state based on the traffic condition as that of power management approach. In the proposed scheme, a node goes to sleep state only when its absence does not create local partition in its neighborhood. We preformed extensive simulation to compare the proposed scheme with existing ones. Simulation results show that the energy consumption is lower with increase in the network lifetime and higher throughput in the proposed scheme

Sharing Printer Beda Network Menggunakan Jaringan Ad Hoc Dengan Aplikasi Mars Wifi Dan Static Routing Protocol

Dunia teknologi saat ini sudah sangat berkembang pesat seiring dengan perkembangan zaman yang sudah mengarah kepada pemanfaatan fungsi perangkat keras secara penuh seperti halnya adalah mesin pencetak dokumen atau sering disebut juga dengan printer. Penggunaan printer sangat dibutuhkan terlebih dikalangan akademisi, perusahaan kecil, menengah, dan atas sudah sangat ketergantungan kepada printer. Untuk menghindari kebutuhan printer yang begitu banyak maka ada solusi dengan cara melakukan sharing printer dimana tidak butuh banyak printer untuk melakukan pencetakan, cukup di share saja printernya kemudian gunakan kabel jaringan dan switch serta router untuk menshare printer dalam skala yang cukup besar. Namun apabila jumlah komputer terus bertambah atau bahkan ada pengguna printer namun dokumennya ada di laptop sedangkan kabel jaringannya sudah tidak cukup maka dibutuhkanlah sebuah teknologi jaringan yang disebut wifi. Tidak banyak printer yang dilengkapi dengan teknologi ini namun dapat dilakukan dengan cara menshare printer pada laptop kemudian menggunakan technology ad hoc pada laptop untuk mensharenya melalui wifi sehingga pengguna laptop lain dapat menggunakan printer tanpa harus terhubung dengan kabel jaringan. Untuk dapat melakukan share printer dengan wifi perlu dipastikan laptop ad hoc terhubung dengan kabel jaringan sehingga dapat melakukan share printer dan menggunakan static routing protocol dari Microsoft windows agar printer dapat di share dengan beda network.Keyword : Ad Hoc, Wifi, Printer, Laptop, Static Routin

Performance improvement for mobile ad hoc cognitive packets network

This thesis was submitted for the award of Doctor of Philosophy and was awarded by Brunel University LondonIn this thesis, focusing on the quality of service (QoS) improvement using per-packet power control algorithm in Ad Hoc Cognitive Packet Networks (AHCPN). A power control mechanism creates as a network-assisted function of ad hoc cognitive packet-based routing and aims at reducing both energy consumption in nodes and QoS requirements. The suggested models facilitate transmission power adjustments while also taking into account the effects on network performance. The thesis concentrate on three main contributions. Firstly, a power control algorithm, namely the adaptive Distributed Power management algorithm (DISPOW) was adopted. Performance of DISPOW was compared to existing mechanisms and the results showed 27, 13, 9, and 40 percent improvements in terms of Delay, Throughput, Packet Loss, and Energy Consumption respectively. Secondly, the DISPOW algorithm was enhanced, namely a Link Expiration Time Aware Distributed Power management algorithm (LETPOW). This approach periodically checks connectivity, transmission power, interference level, routing overhead and Node Mobility in AHCPN. The results show that LETPOW algorithm improves the performance of system. Results show further improvement from DISPOW by 30,25,30,42 percent in terms of delay, packet loss ratio , path lengths and energy consumption respectively. Finally,Hybrid Power Control Algorithm (HLPCA) has presented is a combination of Link Expiration Time Aware Distributed Power management algorithm (LETPOW) and Load Power Control Algorithm (LOADPOW); deal with cross-layer power control applied for transmitting information across the various intermediate layers. LOADPOW emphasis on the concept of transmission Power, Received Signal Strength Indication (RSSI), and the suitable distance between the receiver and the sender. The proposed algorithm outperforms DISPOW and LETPOW by 31,15,35,34,44 percent in terms of Delay, Throughput, Packet Loss,path length and Energy Consumption respectively. From this work, it can be concluded that optimized power control algorithm applied to Ad-hoc cognitive packet network results in significant improvement in terms of energy consumption and QoS
