Heterogeneous wireless networks thesis

Her MS thesis topic was high-speed interconnect and driver-receiver circuit design. Related Info Overview Wireless communication today supports heterogeneous wireless devices with a number of different wireless network interfaces WNICs.

Saving energy also lowers the cost of network maintenance by avoiding frequent and expensive replacement of batteries. In this context, minimizing energy consumption is critical to maintaining operational data links.

The sensed data needs to be routed through multiple hops before reaching the backbone. Types of Network Security There are different types of network security such as: There are two modes of operation of WLAN: Network Security Network Security includes a set of policies and activities designed to protect the integrity of the network and its associated data.

The increase in the popularity of such real-time applications requires that more attention is focused on Quality of Service QoS parameters such as delay, jitter and packet loss in access networks.

In this context, minimizing energy consumption and timely data delivery is critical to maintaining operational data links.

Thesis and Research Topics in Computer Networking

QoS methodologies used for the internet do not apply in this situation due to highly variable wireless channel conditions and thus varying bandwidth constraints, the continually changing network topology, and stringent energy and computational requirements of the sensor nodes.

Its applications can also be found in homes, schools, colleges, and offices. In this talk we will provide an overview of HPWREN, along with an outline of recent results obtained by our newly developed scheduling algorithm.

To propose secure authentication mechanism for cluster-based vehicular ad-hoc networks.

The TDMA based scheduling algorithm limits the number of active nodes and allows a large portion of nodes to sleep, thus saving energy. In such heterogeneous networks, roaming mobile nodes will experience regular handoffs across network boundaries.

Heterogeneous wireless networks thesis solution includes scheduling and routing algorithms. Thesis Topics in Wireless Ad-hoc Networks Following are the list of topics in wireless ad-hoc networks for thesis: Once part of the backbone, a node is required to stay awake continuously for a predefined amount of time.

Scheduling is combined with the creation of a backbone of nodes in charge of providing connectivity to the network and delivering data to the proper destinations. The stations that provide wireless routing are known as access points while the other components such as laptops, smartphones are wireless clients in the network.

The goal of our work is to design novel scheduling and routing algorithms capable of providing good QoS to sensing applications while minimizing the energy consumption of the battery operated nodes. QoS is also influenced by the types of applications a mobile terminal MT is running, user preferences and network usage criteria in different service areas, transmission media and implemented mechanisms.

It includes a distributed scheduling algorithm that allows a large portion of nodes to switch off the NIC thus saving energy.

By being compatible with the IEEE In fact, the VHD algorithm equilibrates the MTs assignment over the available networks by attaching each terminal to the network that has a capacity nearest to the MT requirements. The proposed solution is an energy efficient mechanism for scheduling and routing in heterogeneous wireless sensor networks such as HPWREN.

This is achieved by distributing the MTs over the networks even if the networks have modest performance. The presented model addresses the challenge of working with heterogeneous wireless technologies from the perspectives of the mobile terminals and network nodes.

This thesis presents a novel routing mechanism for HWSNs that achieves large energy savings while delivering data efficiently throughout the network. Under the proposed multi-interface architecture, a mobile terminal can work with multiple network interfaces through common upper layer protocols such as Mobile IPv6.

This technology mainly finds its applications in road and vehicle safety.
