, which can save energy by reducing the traffic flow, and the geo-routing protocol is suitable for applications such as target tracking, and it is necessary to wake the sensor node closest to the target when tracking the target, in order to obtain more precise location information about the target. The route selection is based on the location information of the node, and the reliable routing protocol is mainly to satisfy the reliable QoS of the routing technology.2.

Replace iteratorLet's start by recalling the use of iterators in Java, which can be used with the list and set sets of iterators. The reason is that they all implement the collection interface, and the collection interface has a parent interface called Iterable. Let's look at a case: PublicClass Demo {@Test Public voidDemo () {ListString> List = NewArrayListString>();List.Add"Hello");List.Add"World"); IteratorString>Iterator= List.Iterator (); while(Iterator.Hasnext ()) {String string =Iterator.

fiber uses Chromatography in an orderly manner, which facilitates identification during maintenance and connection. The small size of the optical fiber Band can increase the density of the optical fiber in the optical fiber cable, which can constitute a large number of cores, such as 320 to 3456 cores. It is applicable to the rapidly developing optical fiber access network.Full-Media Self-bearing Optical CableADSS = All Dielectric self-support (ADSS) optical fiber cables. The tensile strength e
