내용이 방대함, 좀더 세분화가 되면 좋을것 같음.
특히 내용의 절반 이상이 통신 프로토콜에 대한 기본기가 없는 경우 이해하기 힘든 경우가 많음.
1. 노드에 대한 사전 설명이 별도로 있으면 좋을 것 같음.
2. 여러 노드가 동시에 데이터를 전송해서 데이터를 사용하지 못하는 경우(충돌,collision)도 -> 충돌(collision)
3. 차동 신호…

My CSMA test currently has some packet loss with CSMA. In my office with the two nodes so close together there really should be no loss at all.

There's been some email interaction on this subject, which I'm posting here so we can track a resolution. I've taken the liberty of doing some minor edits

eMote v. 14. When measuring power usage for CSMA, I noticed that once the radio is turned on it cannot be turned off. The radio class has a TurnOn() method but not a TurnOff(). So for programs that us…

- CSMA/CA的全称是Carrier sense multiple access with collision avoidance
- 就是在Mac层的碰撞协议,主要的作用是为了解决:**如果有多个节点在同时发送数据,这就容易形成数据堵塞和碰撞,导致网络速度变慢的问题**
该协议可以分为两个部分来看:
1.Carrier sence:每个节点在传输之前,先对信道进行监听,看有…

This is related to the test I am performing in #1165.
I have found that when using ContikiMAC with RIME (I think this may also apply to other network stack configurations), if I try to queue up packe…

The request comes from the WWF project folks.
Currently we have a liveliness parameter (which is a time delay) which is configurable from the dll, but the beaconing interval is set in (native) source …

This is wrt eMote .NOW v. 11.2. One program (call it Sender) periodically generates CSMA messages whose payload consists of an ascending counter value. The other (call it Receiver) is a radio signal m…

eMote v63, .NOW
Under CSMA on the .NOW the neighbor list is never populated. The same program under OMAC behaves as expected. Attached is a sample program. You can specify the protocol at the top o…
