This has been partly due to ad hoc wireless networks’ capability to establish connectivity without the need for pre-existing infrastructure, and the fact that these networks are envisioned to support a wide range of embedded applications. It is also worth mentioning that the decrease in the size and cost of sensors has also played a part in increasing the use of WSNs for applications that would not have been considered feasible previ... ... middle of paper ... ...X.

To examine the benefits, the researched algorithm is evaluated after its implementation on top of representative TCP variants NewReno, NewReno with Explicit Loss Notification and Westwood+. Simulation results showed that with the proposed mechanisms, network utilization by native TCP is improved up to an order of magnitude in error-prone wireless networks, while their performance remained protected in a congested environment. The increase in the number of Wi-Fi hotspots for Internet provisioning has been and continues to be remarkable due to the existence of Wi-Fi enabled cellular handsets and portable devices . To address the unreliability of IP based networks, most Internet applications rely on the TCP . It is well known that TCP is designed and tuned fo... ... middle of paper ... ...pecific Requirements - Part 11: Wireless LAN Medium Access Control (MAC) and Physical Layer (PHY) Specifications, IEEE Std.
Paired devices can share voice, data, music, photos, videos, and other information wirelessly (Bluetooth Technology 101: Fast Facts). It is a combination of both hardware inside a device and software used to create the connections. WiFi or Wireless LANs define a short-range wireless network typically used in an office or home setting that allows several users to access the network resources. IEEE 802.11 sets the standard for wireless LAN equipment and speeds and products under this standard are marketed as the WiFi brand (Certification Partners, 2012). When speeds are mentioned, it is typically in reference to the top speeds available but generally, lower speeds are the expectation.
ZigBee standard offers a profile that defines the network layer stack, security, and applications. Developers must be responsible for their own created application profile or integrate with public a profile which is developed by the ZigBee Alliance. ZigBee specification is an open standard which allows manufacturers to develop their own specialized applications requiring low cost and lower energy. The manual was prepared an introduction to the various components of the ZigBee network. After a quick overview of ZigBee, we begin with a description of high level concepts which are used in wireless communications and move to specific protocols required to perform communication standards.

It is an automatic-configured network of mobile devices which are connected by the wireless links. It is a new technique of wireless paradigm for the mobile hosts. These Ad Hoc networks are not like the traditional wireless networks that rely on a fixed infrastructure but these hosts are dependent on each other so that the network is connected always(Advanced Network Technologies Divisionn.d.). This represent a complex distribution system which have available wireless nodes of mobile that can self-organize into temporary and arbitrary topologies of Ad Hoc network freely and dynamically.It provides the users to use internetwork connection without any pre-required infrastructure. Hence we can see a Mobile Ad Hoc networks as an autonomous collection of all the mobile devices such as mobile phone, sensors, laptop etc.
