Energy efficiency has been a hot research topic for many years and routing algorithms have proposed to improve energy prolong lifetime wireless sensor networks (WSNs). Since nodes close the sink usually need consume more forward data of its neighbours sink, they will exhaust quickly. These are called spot we call this phenomenon problem. In paper, an Enhanced Power Efficient Gathering in Sensor Information Systems (EPEGASIS) algorithm is alleviate spots problem from four aspects. Firstly,...

Energy efficiency and energy balancing are crucial research issues as per routing protocol designing for self-organized wireless sensor networks (WSNs). Many literatures used the clustering algorithm to achieve balancing, however, there usually holes near cluster heads (CHs) because of heavy burden forwarding. As problem in lossy WSNs is proved be a NP-hard problem, many metaheuristic algorithms utilized solve problem. In this paper, special method called Centers Searching using Particle...

Recently, wireless sensor network (WSN) has drawn wide attention. It can be viewed as a with lots of sensors that are autonomously organized and cooperate each other to collect, process, transmit data around targets some remote administrative center. As such, may deployed in harsh environments where it is impossible for battery replacement. Therefore, energy efficient routing crucial applications introduce WSNs.

Numerous tiny sensors are restricted with energy for the wireless sensor networks since most of them deployed in harsh environments, and thus it is impossible battery re-change. Therefore, efficiency becomes a significant requirement routing protocol design. Recent research introduces data fusion to conserve energy; however, many do not present concrete scheme process. Emerging machine learning technology provides novel direction makes more available intelligent. In this article, we an...

Abstract In wireless sensor networks (WSNs), devices must be equipped with the capabilities of sensing, computation and communication. These work continuously through non-rechargeable batteries under harsh conditions, batter span nodes determines whole network lifetime. Network clustering adopts an energy neutral approach to extend life. The methods can divided into even uneven clustering. If is adopted, it will cause cluster head (CHs) in vicinity base station relay more data hole...

Wireless body area networks (WBANs) are expected to play a vital role in the field of patient-health monitoring shortly. They provide convenient way collect patient data, but they also bring serious problems which mainly reflected safe storage collected data. The privacy and security data WBAN devices cannot meet needs users. Therefore, this paper adopts blockchain technology store improves Moreover, model based on is proposed our solution. However, brings new problems, for example, that...

Low-latency data access is becoming an upcoming and increasingly important challenge. The proper placement of blocks can reduce travel among distributed storage systems, which contributes significantly to the latency reduction. However, dominant optimization has primarily relied on prior known requests or static initial distribution, ignores dynamics clients' networks. learning technology help center networks (DCNs) learn from historical information make optimal decision. Consider a more...

Following task model consist actuation time, operation length, deadline, profile, copies or maps profile according to type, which can be either preemptive nonpreemptive. The proposed scheme expands search space recursively traverse all feasible allocations for set. A pilot implementation this...

This paper deals with the leader-follower formation control of underactuated autonomous surface vehicles in presence model uncertainties and input constraints. In a formation, an vehicle (ASV) called leader tracks pre-described trajectory other ASVs followers that are controlled to follow desired distance relative bearing. To this end, some adaptive robust techniques adopted guarantee robustness closed-loop system against uncertainties, external disturbances, saturation Based on Lyapunov...

The proton exchange membrane fuel cell as a green power source is suitable replacement of the engine mounted generators in emergency unit more-electric aircraft. Most existing energy management methods for operation cells aircraft refer to hydrogen consumption minimization. But due increasing number electrical components and hence demand aircraft, demand-side should be considered these methods. In order determine effect on size, an efficient load priority model presented integrated into...
