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: NS编程与调试 － NOAH 模块
noah是一个无线路由代理（相对于DSDV ，路由， ... ）只支持直接沟通的无线节点之间或基站和移动节点的情况下移动IP的使用。这使得模拟的情况下多跳无线路由是不受欢迎的。noah不会发送任何路由相关的数据包。-NS programming and debugging- NOAH Module
NOAH is a wireless routing agent that (in contrast to DSDV, DSR, ...) only supports direct communication between wireless nodes or between base stations and mobile nodes in case Mobile IP is used. This allows to simulate scenarios where multi-hop wireless routing is undesired. NOAH does not send any routing related packets. Platform: |

Description: In the next generation of wireless communication systems, there will be a need for the rapid
deployment of independent mobile users. Significant examples include establishing survivable, efficient,
dynamic communication for emergency operations, disaster relief efforts, and military networks. Such
network scenarios cannot rely on centralized and organized connectivity, and can be conceived as
applications of mobile ad hoc networks. A MANET is an autonomous collection of mobile users that
communicate over relatively bandwidth constrained wireless links. Since the nodes are mobile, the
network topology may change rapidly and unpredictably over time. The network is decentralized, where
all network activity including discovering the Platform: |

Description: The proposed routing protocol for Wireless Sensor Network is hierarchical and cluster based. The protocol supports mobility in the Sensor Nodes as well as in the Sink. The entire
protocol is described in terms of two phases namely Setup Phase and Data Forwarding Phase. After deployment of the Sensor Nodes entire sensor field in divided into some logical clusters and each cluster contains Sensor Nodes with different roles such as Gateway Node, Cluster Head Node and Ordinary Sensor Node.
Majority of the computation intensive tasks are carried out in the Sink. Simulation results show the energy efficiency of the proposed protocol. The performance of the proposed protocol
has been compared with that of CBR mobile WSN and results show better performance of the proposed protocol. Future scope of the work is outlined. Platform: |

Description: that monitor certain conditions in different locations and transfer data
through a network to an endpoint called base station. Because WSN nodes are
often deployed outdoors where a direct power outlet may not be available, energy
efficiency becomes a key factor in the design of WSNs. This work proposes an
antenna transmission power optimisation algorithm (TPOA) which dynamically
adjusts the power level of the transmission according to the last received signal
strength indicator (RSSI). The mechanism was implemented and tested on an
XbeeWSNthat uses a modifiedMixed Hop and signalReceived routing for mobile
Wireless Sensor Networks (MHRWSN) protocol. The energy consumption results
have shown that the proposed system can save as much as 76% of power in Tx
operations while maintaining a packet reception rate of above 85% Platform: |
