RPL存储模式下的访问路由表(Contiki / Cooja)

Question

1. I能够成功地运行示例代码(./
2. /6tisch/simple-node)，其中实现了rpl-lite，并且在每60秒网络根之后打印其路由表。由于它使用rpl-lite，只有根节点存储一个路由表。
3. I在本程序中寻找实现(存储模式)的示例代码，并每60秒打印每个节点的路由表。

我在Make文件中添加了"MAKE_ROUTING = MAKE_ROUTING_RPL_CLASSIC“，以启用RPL-经典

#include "contiki.h"
#include "sys/node-id.h"
#include "sys/log.h"
#include "net/ipv6/uip-ds6-route.h"
#include "net/ipv6/uip-sr.h"
#include "net/mac/tsch/tsch.h"
#include "net/routing/routing.h"

#define DEBUG DEBUG_PRINT
#include "net/ipv6/uip-debug.h"

/*---------------------------------------------------------------------------*/
PROCESS(node_process, "RPL Node");
AUTOSTART_PROCESSES(&node_process);

/*---------------------------------------------------------------------------*/
PROCESS_THREAD(node_process, ev, data)
{
  int is_coordinator;

  PROCESS_BEGIN();

  is_coordinator = 0;

#if CONTIKI_TARGET_COOJA || CONTIKI_TARGET_Z1
  is_coordinator = (node_id == 1);
#endif

  if(is_coordinator) {
    NETSTACK_ROUTING.root_start();
  }
  NETSTACK_MAC.on();

  {
    static struct etimer et;
    /* Print out routing tables every minute */
    etimer_set(&et, CLOCK_SECOND * 60);
    while(1) {
        PRINTF("Routing entries: %u\n", uip_ds6_route_num_routes());
      PROCESS_YIELD_UNTIL(etimer_expired(&et));
      etimer_reset(&et);
    }
  }

  PROCESS_END();
}

这些步骤对我有效：

1. 将MAKE_ROUTING=MAKE_ROUTING_RPL_CLASSIC添加到Makefile以确保使用RPL经典模式；默认情况下是打开存储模式的。

     /* Log configuration */
     #include "sys/log.h"
     #define LOG_MODULE "App"
     #define LOG_LEVEL LOG_LEVEL_DBG

1. 将此代码添加到while(1)循环：

      LOG_INFO("Routing entries: %u\n", uip_ds6_route_num_routes());
      uip_ds6_route_t *route = uip_ds6_route_head();
      while(route) {
        LOG_INFO("Route ");
        LOG_INFO_6ADDR(&route->ipaddr);
        LOG_INFO_("/128 via ");
        LOG_INFO_6ADDR(uip_ds6_route_nexthop(route));
        LOG_INFO_("\n");
        route = uip_ds6_route_next(route);
      }

根节点上的输出：

01:00.382   ID:1    [INFO: App       ] Routing entries: 7
