Abstract There are many bridging‐the‐digital‐divide initiatives implemented by various government agencies and non‐governmental organisations throughout the world. Numerous studies have been conducted to identify critical success factors in providing remote rural communities equitable access Information Communication Technologies (ICTs). Malaysia has its fair share of successes failures such initiatives. One initiative, eBario Project, which provided ICTs community Bario, Borneo Malaysia,...

The digital divide continues to be a problem on global scale. Since the pandemic began, there has been widespread media coverage of people being unable work from home or conduct online studies due lack internet access. Many development and design approaches have used accomplish specific rural community objectives, including user-centred, participatory co-design. Each these strategies is effective at accomplishing certain objectives. purpose this research investigate cultural values dimension...

Established knowledge dissemination processes in the HCI community, such as academic publications and conferences, promulgate a systemic exclusion of indigenous research partners. While few individuals from or marginalised communities have published, entire collaborating projects not had opportunity to present their work created process. Thus we argue for more inclusive events bi-annual eBorneo inaugural Namibian fair following principles open space technology community means production...

The purpose of this paper is to present the co-design probes in collaboration with community and apply semiotic triangle model analyse design co-created simulate ideas that can be used for future prototyping networks' setup. Five (5) members participated three (3) activities: one online via a WhatsApp group two in-person workshops at longhouse. collected twenty-five (25) values created seven "Proud Iban" probes. Following model, were analysed then mapped 25 values. Through generative...

In 802.11 wireless infrastructure networks, as the mobile node moves from one access point to another, active connections will not be badly dropped if handoff is smooth and there are sufficient resources reserved in target point. a 5x5 grid of points, within 6x6 regions, by location tracking data mining, we predict mobility pattern with good accuracy. The pre-scanning nodes, along pre-authenticating neighbouring points pre-reassociation used reduce scan delay, authentication delay...

In an IEEE 802.11 Infrastructure network, as the mobile node is moving from one access point to another, resource allocation and smooth hand off may be a problem. If some reliable prediction done on node’s next move, then resources can allocated optimally moves around. This would increase performance throughput of wireless network. We plan investigate hybrid mobility scheme that uses location tracking data mining predict future path node. also propose secure version same scheme. Through...

This paper addresses integration of transformer, which focused on the analysis and design chip especially at high frequencies. The equivalent circuit model is obtained through both measurement EM simulation with scattering parameters extraction. Two typical types transformers have been fabricated 0.25 mum CMOS technology; namely interleaved stacked transformer. These on-chip are designed simulated using Virtuoso Layout Editor in CADENCE software. Physical transformer such as winding scheme,...

The routes in IP networks are determined by the destination address and routing tables each router on path to destination. Hence all packets follow same route until is changes due congestion, link failure or topology updates. IPv4 tried using Type of Service (TOS) field header classify traffic that did not succeed as it was based fair self-classification applications comparison network other applications. As multimedia were quite foreign at initial stage, TOS used uniformly. there different...
