Multilayer Clustered Designing Algorithm is exploited to present MCDA - Hot Spot algorithm; a technique to increase the network throughput by alleviating the impact of hotspot issue on network lifetime. The network nodes in the hot spot region are in a flat layer form in contrast to rest of the network nodes that are grouped into clusters. This design substantially helps in achieving goal above. This...
In a Wireless Sensor Network (WSN), there are a large number of nodes whose power supply and computational capability are limited. The nodes in a wireless sensor network can be fixed or move randomly. Thus in these networks, to forward a data packet from one node to another needs to use specific strategies with very different characteristics. Accordingly the data forwarding strategy among nodes plays...
Multi Criteria Decision Making (MCDM) is useful for choosing a possible objective. The objective is to investigate how far TOPSIS method of MCDM can be utilized for delay sensitive network selection problem.

To achieve a reliable and robust system for environmental monitoring, there is an available technology that can be used to resolve this problem and moreover provide for better living. Wireless sensor networks (WSN) have been successfully applied in many environmental monitoring. An ad-hoc wireless sensor network consists of a number of small and self-power sensing devices (nodes) connected using effective...
Cross-technology communication (CTC) techniques are introduced in recent literatures to explore the opportunities of collaboration between heterogeneous wireless technologies, such as WiFi and ZigBee. Their applications include context-aware services and global channel coordination. However, state-of-the-art CTC schemes either suffer from channel inefficiency, low throughput, or disruption to existing...
Recent research on CTC (cross-technology communication) demonstrates the viability of direct coordination among heterogeneous devices (e.g., WiFi and ZigBee) with incompatible physical layers. Although encouraging, current solutions suffer from either severe inefficiency in channel utilization or low throughput using limited beacons. To address these limitations, this paper presents C-Morse, which...
In this paper, we investigate the delay and delay-constrained throughput performance of a point-to-point wireless-powered communication system, where one node, e.g. a user equipment (UE), is powered by the wireless energy transferred from the other node, e.g. an access point (AP), and uses the harvested wireless energy to send data to the other node. Our focus is on the delay performance of sending...
With an advancement towards the paradigm of Internet of Things (IoT), in which every device will be interconnected and communicating with each other, the field of wireless sensor networks has helped to resolve an ever-growing demand in meeting deadlines and reducing power consumption. Among several standards that provide support for IoT, the recently published IEEE 802.15.4e protocol is specifically...
Wireless sensor network is an application tools which play a important role in monitoring remote environment and tracking of target.

All the AMON's work in ADHOC...
Previous studies have shown that opportunistic routing (OR) can significantly improve the performance of wireless multi-hop networks, such as wireless adhoc networks and wireless sensor networks. However, most existing opportunistic routing schemes only consider node location as the priority metric in relay selection, where packets may accumulate in relays' packet buffer, especially in data intensive...
