Machine to (M2M) communication has gained much momentum in the recent past, both within academia and across different industries. Many of M2M applications are required send data server connected directly or indirectly network such as 3GPP network. This requires connecting millions devices, apart from usual mobile However, this imposes a major deployment management challenge, since was originally not designed support billions simultaneous connections. paper discusses practical scenario...

Edge networking has become an important technology for providing low-latency services to end users. However, deploying edge network does not guarantee continuous service mobile Mobility can cause frequent interruptions and delays as users leave the initial serving edge. In this paper, we propose a solution provide transparent continuity in large-scale WiFi networks. The contribution of work three parts. First, ARNAB architecture achieve continuity. term means rabbit Arabic, which represents...

In a tree-structured ZigBee wireless sensor network, nodes close to the root of tree (i.e., hot-spot nodes) may exhaust their power earlier than those distant from due heavy loads on packet forwarding. This problem is inherent in networks and demand extra energy recover failures nodes. this paper, backbone-aware topology formation (BATF) scheme proposed alleviate problem. BATF utilizes power-rich form backbone that does not suffer Each node independently initiates network attracts...

Current wireless enterprise networks pose a user access management challenge. That is, an network should provide service to diverse devices whose resource allocation policies be treated differently according the company policy. Software-defined (SDN) is suitable candidate meet challenge due its centralized and dynamic control features. Based on OpenFlow protocol, which primitive realize software-defined network, this work implements bandwidth slicing technique commercial WiFi AP. The...

SUMMARY Co‐channel interference seriously influences the throughput of a wireless mesh network. This study proposes an end‐to‐end channel allocation scheme (EECAS) that extends radio‐frequency‐slot method to minimize co‐channel interference. The EECAS first separates transmission and reception packets into two channels. can then classify state each as transmitting, receiving, interfered, free, or parity. A node initiates communication session with quality service requirement propagate...

Due to the facts of wireless data usage being increasing faster now than ever before and more multimedia content generated by users uploaded network, multi-user MIMO (MU-MIMO) technology would be crucial improve LTE-A uplink spectral efficiency for meeting service demands. On other side, adopting clustered SC-FDMA as multiple access scheme means that a User Equipment (UE) can allocated one cluster which consists contiguous RBs (this is contiguity constraint). Moreover, all UE must use same...

In this paper, we present an architecture for transparent service continuity cloud-enabled WiFi networks called ARNAB: ARchitecture traNsparent viA douBle-tier migration. The term arnab means rabbit in Arabic. It is dubbed the proposed because a mobile-user with ARNAB behaves like hopping through infrastructure. To deliver continuous services, deploying edge clouds not sufficient. Users may travel far from initial serving and also perform multiple handoffs during mobility. solve this,...

Crossover nodes have been utilized to achieve smooth handoffs for micro mobility management schemes. IEEE 802.11s supports proxy-based frame delivery services mobile hosts roaming within a wireless mesh network (WMN). Discovering crossover node in WMNs, however, faces several challenges due intrinsic properties of networks. This paper identifies these and proposes scheme suitable discovery under WMNs. is characterized by source-oriented, MAP-centric, per-source. It can be performed off-line...

Machine to (M2M) communication has gained much interest in the recent past, both within academia and across different industries. Power saving become a priority issue recently due accelerated growth of mobile devices with more processor power, storage capacity, better display technology richer-applications. It assumes even greater significance when it comes M2M since unlike hand-held which possibility get re-charged after certain period time, many overall life is almost equal its one-time...

The need for multimedia communication through wireless media brings development of 4G cellular networks. Long Term Evolution (LTE) is one standards and specified in 3GPP. In an LTE system, home base station (HeNB) designed indoor usage. Since packets are always routed back to the core network before destination, if two user equipments (UEs) stay same HeNB, routing path detour results longer packet delivery delay, jitters thus lower data throughput. As a result, idea local IP Access (LIPA)...

In this paper, we propose a controller-assisted distributed (CAD) load-balancing mechanism for the ZigBee network containing multiple personal area networks (PANs). Shifting enforcement part from central controller to PANs, each PAN in CAD maintains its load status whereas simply node numbers of PANs and list switch pairs which is formed two nodes nearby different denoting possible between PANs. Upon perceiving unbalanced, just provides heavy-loaded pair an offload threshold so that enforces...

A self-optimization function called mobility robustness optimization (MRO) is to gradually find-tune the handover configuration parameters by analyzing history. It expected that smart antenna can help MRO further decrease number of radio link failures. However, current does not take into consideration. This paper proposes an enhanced method which supports base stations with antennas. idea beam pattern pair a source angle and target angle. classification also proposed utilizes historical...
