I will likely contribute mostly to areas which are near to my own research since I know more about these things without having to much extra work. Here are a few things about me:

Simulation

2009-06-09T20:09:45Z

Jernst:

== About ==
Simulation is a method to perform experiments which may not be possible or feasible in the real world.

== Benefits of Simulation ==
The reasons why the real world experiment may not be performed may vary. For example, an experiment may otherwise be too costly (in terms of equipment), too dangerous (disaster scenarios, extreme environments), or to save time. A simulation can often run much faster than an experiment would in real life. This is helpful in many cases such as environmental simulation since the amount of time being modelled is often very large. In applied computing, such as wireless network design, simulation can help to determine which designs are most promising before implementation in real equipment which often saves time, effort and money.

== Drawbacks of Simulation ==
At the same time, simulation is often criticized for not being a realistic representation of the real world. In wireless network simulation for example, critics often argue that performance in the real world is not nearly as good as the simulations often predict. However, some of these problems may be eventually improved with more realistic models. Another drawback of simulation is reproducibility of experiments. Unless there are standardized simulation tools being used, it is often difficult to compare or evaluate results. At the same time, the standardized tools often do not provide the functionality required for a given experiment so customization is necessary.

Linux

2009-06-09T19:52:09Z

Jernst:

Linux is an open source kernel, though it is commonly used to refer to the entire operating system based upon that kernel. It comes in many flavours (distributions, or "distros" for shourt), the ones most commonly used by [[CompSci.ca]] members are [[Ubuntu]] and [http://www.gentoo.org Gentoo]. Some also use [http://www.archlinux.org archlinux].

Debian

2009-06-09T19:45:28Z

Jernst: Saw a Ubuntu page and thought Debian deserved one as well :P

Debian is a free operating system which uses the Linux kernel. It makes use of many [[GNU Project]] tools for some of the basic OS operation. [[Ubuntu]] was originally based on Debian Linux. Debian was started in 1993 by Ian Murdock. From the Debian website: Debian is pronounced /ˈde.bi.ən/.

Wireless Mesh Network

Jernst:

== Definition and Overview ==
A [[Wireless Mesh Network]] (WMN) is a multi-hop wireless network. Usually, WMNs consist of Mesh Routers (MR), Mesh Clients (MC), and Gateways (GW). Mesh Routers and Gateways form the infrastructure of the network and provide access to the Mesh Clients which are often laptops, cellphones, PDAs and other devices. Often the Mesh Routers are assumed to be fixed and non mobile but this is not always the case. The Mesh Routers are also often assumed to have access to greater resources (CPU, Memory) than MCs. These characteristics separate a WMN from a [[mobile ad hoc network]] (MANET). In a MANET, all nodes are generally limited by battery life, CPU and Memory resulting in protocols and algorithms which are tailored to conserving these resources. In a WMN, the MRs can be taken advantage of when designing protocols that have greater performance.

In a WMN, the MRs and GWs form a mesh structure. This structure allows redundancy which can be exploited in order to provide greater throughput or enhanced reliability compared with solutions such as wireless local area networks (WLAN).

== Areas of Research / Open Problems ==
* Scheduling, Load Balancing & Resource Allocation
* [[Hidden Node Problem]]
* [[Exposed Node Problem]]
* Security
* Routing Algorithms
* Multiple Radio / Multiple Channel Problems
* Scalability
* Collaborative Caching

== How WMN Research is Conducted ==
Research in this field is often conducted using simulation tools, testbed environments or a hybrid of both approaches. The most popular is [http://www.isi.edu/nsnam/ns/ Network Simulation 2] (NS2). There is also a successor to this tool being developed called [http://www.nsnam.org/ NS3]. The main difference being that NS3 has been designed with wireless simulation in mind while NS2 was originally a wired simulation only. There are many testbed environments for WMNs. One of the most well-known is [http://pdos.csail.mit.edu/roofnet/doku.php MIT Roofnet]

There is also a successor to this tool being developed called [http://www.nsnam.org/ NS3]. The main difference being that NS3 has been designed with wireless simulation in mind while NS2 was originally a wired simulation only. There are many testbed environments for WMNs.

Jernst: /* Wireless Mesh Network Research Groups and Projects in Canada */

== Definition ==
A [[Wireless Mesh Network]] (WMN) is a multi-hop wireless network. Usually, WMNs consist of Mesh Routers (MR), Mesh Clients (MC), and Gateways (GW). Mesh Routers and Gateways form the infrastructure of the network and provide access to the Mesh Clients which are often laptops, cellphones, PDAs and other devices. Often the Mesh Routers are assumed to be fixed and non mobile but this is not always the case. The Mesh Routers are also often assumed to have access to greater resources (CPU, Memory) than MCs. These characteristics separate a WMN from a [[mobile ad hoc network]] (MANET). In a MANET, all nodes are generally limited by battery life, CPU and Memory resulting in protocols and algorithms which are tailored to conserving these resources. In a WMN, the MRs can be taken advantage of when designing protocols that have greater performance.

In a WMN, the MRs and GWs form a mesh structure. This structure allows redundancy which can be exploited in order to provide greater throughput or enhanced reliability compared with solutions such as wireless local area networks (WLAN).
