Innovations in technology that have enabled efficient wireless tiny devices propelled the concept of Internet of Things. It is expected that mobile data traffic will experience 8-fold growth between 2015 and 2020 and the number of mobile connected devices will reach 11.6 billion by 2020. Main factors of this exponential growth and wide acceptance are the integration of several technologies and communications...
Wireless sensor networks (WSNs) have wide applications in environmental monitoring fields. Many algorithms were proposed for efficient information gathering. Especially the cluster based routing schemes are getting attention due to their energy efficiency. But in most of the clustering schemes, the base station (BS) which is used to gather the information is assumed to be located far from the field...
In this paper the performance analysis of a routing algorithm for MANETs called Service Zone Gateway Prediction (SZGP) is presented. This is a non-cooperative and hybrid type of routing with a hierarchical multilayered structure, incorporating pre-computed multipath hop-by-hop distributed connectivity. The goal is balance of the load among the nodes and reliable and energy efficient communication...
Multi-level clustering offers the scalability that is essential to large-scale ad hoc and sensor networks in addition to supporting energy-efficient strategies for gathering data. The optimality of a multi-level network largely depends on two design variables: 1) the number of levels and 2) the number of nodes operating at each level. We characterize these variables within a multi-hop multi-level...
Wireless nodes in MANET present stringent resource constraints such as limited battery power and storage capacity, so energy aware cross-layer design is essential to improve the battery life. For prolonged network operational time, energy conservation is a critical issue in routing protocol design in ad-hoc wireless networks. Regardless of the energy saving issues, the conventional AODV routing protocol...
In Wireless Nanoscale Sensor Networks (WNSN), collision problems are unlikely to happen, and therefore data aggregation should be encouraged to save power consumption. On the other hand, molecular absorption is non-negligible in Terahertz band so that signal impairment should consider free space path loss and molecular absorption simultaneously. In this paper, we consider energy efficient data aggregation...
Advancement of medical science brings together new trend of proactive health care which gives rise to the era of Wireless Body Area Networks (WBAN). A number of issues including energy efficiency, reliability, optimal use of network bandwidth need to be considered for designing any multi-hop communication protocol for WBANs. Energy consumption depends on many factors like amount and frequency of forwarding...

Wireless Sensor Networks need energy efficient protocols for communication and data fusion to consolidate data and prolong the lifetime of the network. In this paper, an adaptive hierarchical clustering and routing method has been proposed. This clustering and routing method is based on maximum bottleneck energy routing (MBER) from a node to the sink. This method favors the routes with the highest...
Source routing techniques like Trajectory Based Forwarding (TBF) are suitable for dense wireless sensor networks (WSNs) due to their low power requirement. Though usual opportunistic coordination adds reliability to TBF, it also increases delay and coordination complexity. Alternatively, this work proposes the use of multiple cooperative relays within every single hop of a trajectory so that two adjacent...
Device-to-Device (D2D) communication is a promising technology for various applications in upcoming 5G networks. This new communication paradigm has a lot to offer in terms of increased spectral efficiency, throughput and reduced communication delay. However, challenges like interference, overhead and energy efficiency still exist In fact, energy-efficiency is considered as one of the key enablers...

During the last decade, we have witnessed a major transition from computation- to communication-centric design of integrated circuits and systems. In particular, the network-on-chip (NoC) approach has emerged as the major design paradigm for multicore systems-on-chip (SoC). The major challenges in traditional wire-based NoCs are the high latency and power consumption of the multi-hop links. By inserting...
