Over the past few years, rapid advances in wireless broadband networks have been driving the evolution of communication and network technologies towards next generation omnipresent computing environments. If a mobile station velocity is high and its movement pattern is irregular, unnecessary handovers likely occur more frequently, and then a seamless handover algorithm between heterogeneous wir...

Next generation wireless network is foreseen as the combination of heterogeneous wireless networks capable of providing enhanced services to mobile users. Vertical handoff is a crucial issue in providing service to mobile users, in a heterogeneous network. To maintain continuous service during vertical handoff period, the handoff procedure should consider the noise and interference in the netwo...

By taking advantage of the ever growing deployment of wireless networks, the automotive industry is increasingly enabling vehicles to communicate with one another and with the infrastructure, with benefits to information delivery and safety on the road. Vertical Handovers can be used to ensure that the Quality of Service demanded by applications (e.g., throughput, latency) is met while the vehi...

Wireless technology has developed a significant part of communication and for the data transmission. Wireless LAN effectively fulfills the necessities within buildings and campus environments. Emerging security measures for the WLAN is a foremost issue when compared to the security features of LAN. Wireless access points mainly fall into three categories: minor business and home networks, enter...

Certificate based authentication of parties provides a powerful means for verifying claimed identities, avoiding the necessity of distributing shared secrets beforehand. Whereas Wi-Fi networks present security deficiencies, they manage to highly penetrate into the wireless market in a great degree due to their low cost, easy administration, great capacity, IP-oriented nature, etc. Considering W...

To provide uninterrupted service to all subscribers in a wireless network, we need to incorporate a low cost, flexible Heterogeneous network which will be able to link with any kind of network for efficient spectrum utilization, hence improved system capacity. In this connection, Wi-Fi/ Wi MAX integrated network seems to be an ideal solution as it is able to provide easy deployment, high speed ...

On the road towards 5G, a proliferation of Heterogeneous Networks (HetNets) is expected. Sensor networks are of great importance in this new wireless era, as they allow interaction with the environment. Additionally, the establishment of the Internet of Things (IoT) has incredibly increased the number of interconnected devices and consequently the already massive wirelessly transmitted traffic....
