Description: Mobile IP是NS中由SUN公司开发的无线--有线模拟模块,它比CMU/Monarch引入的无线模块功能更为强大。IETF提出Mobile IP协议以来，经过各方面的共同努力Mobile IP协议已经日趋完善，相应的技术也逐渐走向成熟。Mobile IP使得人们不再拘泥于时间和空间，可以随时随地的与Internet上的其他网络节点进行通信，不会因为位置的变化而造成通信中断。-Mobile IP is the NS developed by SUN wireless cable simulation module, which more than CMU/Monarch introduced a more powerful wireless module. IETF has proposed Mobile IP protocol, through the joint efforts of all aspects of Mobile IP protocol has become more perfect, the corresponding technology is gradually maturing. Mobile IP makes it no longer rigidly adhere to time and space, anytime, anywhere with the Internet, other network nodes to communicate, and does not change the location of communication interruption caused.

Description: Due to the rapid growth of Wireless Communications devices, it is now believed that the relevance of Multi-Radio devices will highly increase in the near future. The research community has been trying to extend their analysis and simulation models so as to include this type of nodes.
This is also the case of the Network Simulator framework, and there has recently been quite a large interest from its community to extend its mobile node architecture so as to be able to include more than one radio interface to work simultaneously.
After analyzing the different solutions that were available, we propose a set of changes to be done, so as to be able to use devices having multiple interfaces within the ns-2 framework. These changes and modifications are summarized in the howto "Adding Multiple Interface Support in NS-2", Platform: |

Description: A Tutorial of 802.11 Implementation in ns-2 -Ns-2 [1] is a packet-level simulator and essentially a centricdiscrete event scheduler to schedule
the events such as packet and timer expiration. Centric event scheduler cannot accurately emulate
“events handled at the same time” in real world, that is, events are handled one by one. However,
this is not a serious problem in most network simulations, because the events here are often
transitory. Beyond the event scheduler, ns-2 implements a variety of network components and
protocols. Notably, the wireless extension, derived from CMU Monarch Project [2], has 2
assumptions simplifying the physical world:
(1) Nodes do not move significantly over the length of time they transmit or receive a packet.
This assumption holds only for mobile nodes of high-rate and low-speed. Consider a node with the
sending rate of 10Kbps and moving speed of 10m/s, during its receiving a packet of 1500B, the
node moves 12m. Thus, the surrounding can change significantly and cause reception Platform: |

Description: Abstract—In this paper we propose the channel assignment
scheme for multi-channel wireless mesh network (WMN), where
each mesh router is equipped with multiple radio interfaces. In
real WMN the number of radio interfaces is much higher than
the number of non-overlapping channels, which causes a lot of
connections between mesh nodes operate on the same radio
channel. Increasing number of simultaneous transmissions on the
same channel causes interference, which limits network capacity.
This paper presents a new centralized channel assignment
scheme called first random channel assignment algorithm
(FRCA). This algorithm efficiently utilizes radio interfaces to
achieve improvement of the network capacity. NS-2 simulator
was used to evaluate the performance of proposed solution and
simulation results were compared with others channel
