To do that, you must add in the options section: A man page is available for both commands. By default an embedded web server will be started on the controller node and will listen on the port this can be disabled with the -n option. It is useful for debugging purpose.
Test and adjust scenario to have a nice progression of the load. A user is considered online when he has send a presence: The module is included in the source and binary distribution of Tsung.
The command will print the current log directory created for the test, and wait until the test is over.
This version adds an new option for a session. For example, it has been used to analyze cluster symmetry is the load properly balanced.
Alternatively rsh is also supported. No need to write complex scripts. They are all represented as a graphic. It is released under the three-clause BSD License. A new subdirectory is created for each test using the current date and time as name, e.
Dynamic scenarios only requires small trivial piece of code. Add the -u option to enable parent proxy, and use -I serverIP to set the IP and -P portnumber to set the port of the parent. A session file will be created.
Wait for the end of the test or stop by hand with tsung stop reports can also be generated during the test see Statistics and Reports: Hence if you use a local ack with a request that do not require a response from the server presence for ex. The proxy is listening to port The list name is determined from the JID, e.
To do that, set a request with global ack it can be the first presence msg: This is highly dependent of the application and of the size of the target server s. Tsung is for example one of the only tool to benchmark SOAP applications Monitoring of the target server s to analyze the behaviour and find bottlenecks.
You can use Tsung to simulate tens of thousands of virtual users. Launch benchmark with your first application parameters setup: Warning this will considerably slow down Tsung, so use with care.
For HTTP, you can configure the recorder to use a parent proxy but this will not work for https. It removes the client from the list of Online users, and moves them into the list of Connected users. There are 3 possibilities using the ack attribute: Tsung produces statistics regarding: There is no recorder for Jabber, so you have to write your sessions by hand.
It is possible to generate graphs during the benchmark as statistics are gathered in real-time. An Erlang agent can gather information from the target server s.
The Jabber plugin does not parse XML; instead it uses packet acknowledgments. One should take care of properly seeding the server database in order to ensure that such a list exists.
This will start a proxy listening to port and will proxy requests to You can change the port with -L portnumber. If you want to switch back to connected before going offline, you can use a presence: Calculate the normal duration of the scenario and use the interarrival time between users and the duration of the phase to estimate the number of simultaneous users for each given phase.
Analyze results, change parameters and relaunch another benchmark. The default plugin is http. It is released under the EPL License. You can use a different encoding, like in:. Published: Mon, 26 Mar Link Lifetime based Border Node (LLBN) Protocol for Vehicular Ad Hoc Networks.

Request PDF on ResearchGate | Link Lifetime based Border Node (LLBN) Protocol for Vehicular Ad-Hoc Networks | Vehicular ad hoc network (VANET) attracts rising attentions of researchers for safety. These networks have many challenging characteristics such as high mobility, fast changing topology and limitation of bandwidth.
We proposed LLBN (link lifetime based border node protocol) by taking advantage of BMFR for bandwidth utilization and link life time to avoid link failure.
Full Paper. Hence in order to improve the network lifetime, we need to enhance the energy efficiency. In this paper we propose Centralized Border Node based Cluster Balancing (CBCB) protocol, which evenly distributes the load equally among the clusters to improve network lifetime.
