Surge_Reliable不能通讯的问题

在tinyos－help上面找到的，也是一个困扰了我们一个多月的东西

TMD的crossbow

Thanks to everyone,
the problem was with PhotoTempM.nc - after copying it to micasb directory I can finally see my other MICAz motes with Surge Reliable app.

In MPR users guide there is mentioned where the correct PhotoTempM.nc is located, but nobody tells what to do with it - maybe in the next version it can be mentioned that it should be copied to micasb directory, otherwise users - like me - don't pay much attention to it.

Thanks once again.

Libor.

The structure of the TOS_Msg

记忆中的深蓝 — Thu, 11 Aug 2005 10:45:00 GMT

       看了一个下午，终于明白了Tinyos下的Message packet ——TOS_Msg其实就是用typede声明的一个结构体，完整的说明在头文件AM．h这个文件里面找到。以下是TOS_Msg的结构：
typedef struct TOS_Msg
{
/* The following fields are transmitted/received on the radio. */
uint16_t addr;
uint8_t type;
uint8_t group;
uint8_t length;
int8_t data[TOSH_DATA_LENGTH];    //TOSH_DATA_LENGTH=29
uint16_t crc;
/* The following fields are not actually transmitted or received
   * on the radio! They are used for internal accounting only.
   * The reason they are in this structure is that the AM interface
   * requires them to be part of the TOS_Msg that is passed to
   * send/receive operations.
   */
uint16_t strength;
uint8_t ack;
uint16_t time;
uint8_t sendSecurityMode;
uint8_t receiveSecurityMode;
} TOS_Msg;
The addr field specifies the destination address (a moteID or the broadcast address). The group field specifies a channel for motes on a network. If a mote receives a packet with a different group ID, the packet is dropped. The type field specifies which handler to be called at the AM level when a packet is received. The length field specifies the length of the data portion of the TOS_Msg. Packets have a maximum payload of 29 bytes. The data portion consists of an array of 29 bytes (as specified by TOSH_DATA_LENGTH). The unsigned two byte field crc follows. When sending, the crc is incrementally calculated as each byte of the packet is transmitted.
      So, the maximum length of a transmitted TOS_Msg is 36 bytes (addr(2 bytes) + type(1 bytes) + group(1 bytes) + length(13 bytes) + data(29 bytes) + crc(2 bytes) = 36 bytes).
      虽然最大长度是36个字节，但是除去各种开销，有效字节只有29个
• sendingNode (2 bytes) – the node that has sent the packet.
• originNode (2 bytes) – the node that generated the packet.
• seqNo (2 bytes) – the sequence number of the packet.
• hopCount (2 bytes) – the number of hops the packet has travelled.
• data[21] (8 bytes) – the payload field of length 21 bytes.

What is TinyOS?

记忆中的深蓝 — Tue, 09 Aug 2005 16:34:00 GMT

开张了哈哈

TinyOS is an open-source operating system designed for wireless embedded sensor networks. It features a component-based architecture which enables rapid innovation and implementation while minimizing code size as required by the severe memory constraints inherent in sensor networks. TinyOS's component library includes network protocols, distributed services, sensor drivers, and data acquisition tools – all of which can be used as-is or be further refined for a custom application. TinyOS's event-driven execution model enables fine-grained power management yet allows the scheduling flexibility made necessary by the unpredictable nature of wireless communication and physical world interfaces.

TinyOS has been ported to over a dozen platforms and numerous sensor boards. A wide community uses it in simulation to develop and test various algorithms and protocols. New releases see over 10,000 downloads. Over 500 research groups and companies are using TinyOS on the Berkeley/Crossbow Motes. Numerous groups are actively contributing code to the sourceforge site and working together to establish standard, interoperable network services built from a base of direct experience and honed through competitive analysis in an open environment.
