Heterogeneous Wireless Sensor Network (WSN) comprises of sensor nodes with distinctive capability, for example, diverse computing power and sensing range. Contrasted with homogeneous WSN, arrangement and topology control are more perplexing in heterogeneous WSN. Distinctive energy efficient clustering protocols for wireless sensor networks systems and thinks about these protocols on a few focus...

Wireless Sensor Networks (WSNs) are networks of autonomous nodes used for monitoring an environment. In designing WSNs, one of the main issues is limited energy source for each sensor node. Hence, offering ways to optimize energy consumption in WSNs which eventually increases the network lifetime is strongly felt. Gravitational Search Algorithm (GSA) is a novel stochastic population-based meta-...

With the advancement in wireless communication technology, various networks exists simultaneously. The variation in wireless network parameters is imprecise in nature. To handle this imprecise data fuzzy logic can be used as an important tool for wireless network algorithms. Application of fuzzy logic/fuzzy controller in wireless communications is presented in this paper. The objective of this ...

In this paper, we propose the Ad-hoc CEllular NETwork (ACENET), a heterogeneous wireless network architecture for 3.5 generation (3.5G) and fourth-generation (4G) mobile systems. We propose an IP-based integrated wireless routing scheme for the integration of heterogeneous wireless networking technologies in 3.5G and 4G ACENET. We also propose an integrated wireless MAC scheme for 4G ACENET. AC...

In Wireless Mobile Cellular Networks, users usually move between heterogeneous networks. In this type of environment, handoff procedure algorithm, handoff decision and its management is very important issue. Wireless Mobile Cellular Network supports the handoff process for users between various wireless technologies such as WLAN, CDMA and modern 3G networks. Heterogeneous networks are integrate...

Multimedia streaming over heterogeneous wireless networks has attracted significant interest in recent years from both telecom network operators and end users. However, the heterogeneity of the wireless network makes it very difficult to synchronize real-time multimedia streaming across different types of end-user devices across different wireless networks. In addition, with different delay and...

TCP congestion control works well in wired Internet network but it is difficult to determine a good congestion window in a heterogeneous wireless network that consists of the wired Internet and various types of wireless networks. Therefore, we propose herein a novel adaptive window congestion control, namely TCP-Taichung, for TCP connections in heterogeneous wireless networks. The proposed RTT-...

With the rapid growth of wireless technologies, there will be coexistent heterogeneous wireless networks environment within a few years. For example, there may be coexistent current wireless LAN systems based on widely available IEEE 802.11 and a wireless system based on proprietary wireless standard with different AAA mechanisms such as RADIUS and Diameter. In case of being coexistent the hete...

In the development of the wireless communication of the future, mobility management and existing heterogeneous wireless networks integration in next generation or 4G wireless networks are developing trend. Such an environment poses a significant challenge: how can we choose an appropriate Network Access Point (NAP) to achieve load balance and offer high quality communication in heterogeneous wi...
