In the last decent, number of Internet Things (IoT) health-based paradigm reached to a huge users, services, and applications across different disciplines. Thus, hundreds wireless devices seem be distrusted over limited or small area. To provide more efficient network, software-defined network (SDN) thought good candidate deal with these users. this work, after novel SDN algorithm is proposed for hospital environment, it also designed integrated into an Health (IoHT) paradigm. The called...

The definition of the bandwidth efficiency (BE) cognitive cooperative network (CCN) is ratio between a number licensed slot(s) or sub-channel(s) used by unlicensed users to transmit single data packet from transmitter destination, and relay(s) destination. This paper analyzes improves BE in underlay CCN with new reactive relay selection under interference power constraints. In other words, this studies how use efficiently. To end, method named as Relay Automatic Repeat Request (RARQ)...

Abstract Two basic strategies have developed by network designers to deal including errors. adding extra information data before sending. such approach is comprise sufficient make destination infer what the sent should be, or it possible add only let that errors been occurred, however not which error then ask re-send defected data. Previous strategy utilizes correcting mechanism and latter uses detecting mechanism. Utilize of named as Forward Error Correction (FEC). In this thesis, sliding...

This paper presents the results of our computer simulation for delays experienced by voice packets over WiMAX 802.16e protocol running an enterprise packet network connected to public internet. In we analyzed effect size, core link speed, Internet service provider wireless distance, base station range, and distance in internet parameters that amount delay a embedded IP network. this study, all are fixed their default values current parameter changed so is varied between minimum maximum...

This paper demonstrates the usage of novel cognitive methods that improve throughput a WIMAX network by minimizing packet loss. The effects ant colony and fastest path routing algorithms on are investigated. combination Time Division Multiple Access (TDMA) Orthogonal Frequency (OFDMA) spectrum sharing techniques is used. Data loss rate minimized for real-Time voice video transmissions. unicast mobile multimedia with improved system provided both methods, even small node count.

This study proposes a long lived routing method which is also based on Associativity such as ABR (Associativity Based Routing) for real time applications. The main purpose of our work improving the algorithm in order to reduce outage nodes and decreasing number reconstructions required keep communication. performance compared with other long-lived relay selection algorithms real-time

A cognitive method called most congested access first (MCAF), minimizing the packet loss ratio and improving throughput of a multihop mobile WiMAX network, is proposed. MCAF combines both time division multiple orthogonal frequency methods. additionally uses spectral aid buffer management methods, which are proposed in this paper, to manage spectrum packets buffers. By using these novel real-time video voice transmission achieved, data rate minimized, system per node improved. Effects...

By the introduction of all IP networks with smart homes, phones, car multimedia systems wearable technologies and TV’s, number internet related devices applications have increased. This has generated an increased quantity bandwidth usage in packet switching networks. Therefore, betterment system performance become more significant. Thus, there is a large works literature attempting to improve network performance. For this purpose, generally modifications used methods structures are...

Efficient utilization of available resources and the avoidance overload conditions have high importance for any communication network. For a CSMA based VANET wireless bandwidth must be shared fairly among all nodes. In network are in dynamical structures. Thus, if congestion control is not provided broadcast communication; lower priority applications may use entire spectrum cause starvation some important applications. this work it shown that our proposed MCAF (Most Congested Access First)...

In this study, the fastest path algorithm which is known as a routing method from source to destination and Ant colony be adaptable dynamic changes in network are compared for average hop counts, power consumption packet arrival delays by implementing mobile simulation. Even counts both algorithms reach almost same value at simulation results, since it seen that provides less delay with respect algorithm, thought may more useful than real time voice or video transmissions.
