无线传感网：linux上 6lowpan与ieee802154（zigbee）的实现比较

应用层

https://github.com/JulienMasson/6LoWPAN/blob/master/webserver/webserver.c

网络层

Ipv6协议族：

路由可以基于ipv6+RPL协议；

ieee802154协议族：

传输控制也没有问题，但是路由协议又该如何解决呢？

mac子层：实现各自的网络设备驱动+MLME驱动

6lowpan子层：

kernel3.10 6@lowpan.c

Kernel4.0 @/linux-4.0/net/ieee802154/6lowpan/core.c

static const struct net_device_ops lowpan_netdev_ops = {

.ndo_init                = lowpan_dev_init,

.ndo_start_xmit                = lowpan_xmit,

.ndo_set_mac_address        = lowpan_set_address,

};

static struct ieee802154_mlme_ops lowpan_mlme = {

.get_pan_id = lowpan_get_pan_id,

.get_phy = lowpan_get_phy,

.get_short_addr = lowpan_get_short_addr,

.get_dsn = lowpan_get_dsn,

};

static struct header_ops lowpan_header_ops = {

.create        = lowpan_header_create,

};

注册网络设备方式：

static struct rtnl_link_ops lowpan_link_ops __read_mostly = {

.kind                = "lowpan",

.priv_size        = sizeof(struct lowpan_dev_info),

.setup                = lowpan_setup,

.newlink        = lowpan_newlink,

.dellink        = lowpan_dellink,

.validate        = lowpan_validate,

};

static inline int __init lowpan_netlink_init(void)

{

return rtnl_link_register(&lowpan_link_ops);

}

mac802154层：wpan.c

static struct header_ops mac802154_header_ops = {

.create                = mac802154_header_create,

.parse                = mac802154_header_parse,

};

static const struct net_device_ops mac802154_wpan_ops = {

.ndo_open                = mac802154_slave_open,

.ndo_stop                = mac802154_slave_close,

.ndo_start_xmit                = mac802154_wpan_xmit,

.ndo_do_ioctl                = mac802154_wpan_ioctl,

.ndo_set_mac_address        = mac802154_wpan_mac_addr,

};

struct ieee802154_mlme_ops mac802154_mlme_wpan = {

.get_phy = mac802154_get_phy,

.start_req = mac802154_mlme_start_req,

.get_pan_id = mac802154_dev_get_pan_id,

.get_short_addr = mac802154_dev_get_short_addr,

.get_dsn = mac802154_dev_get_dsn,

};

注册网络设备方式：

mac802154_add_iface(struct wpan_phy *phy, const char *name, int type)

{

。。。。。

err = mac802154_netdev_register(phy, dev);----》register_netdev（）注册核心层的网络设备’

如何与mac和物理层通信

通过虚拟化网络技术，类似：VLAN
