To select the applied access scheme, three classes are defined, namely the mobility class, the service class and the environment class.
The nodes are not statically assigned to the mobility class; depending on changes in its mobility in certain periods of the day, assigned class may change.
The mobility class are (a) mobile users and (b) nomadic users with a rather low terminal velocity.
(2) If a node wishing to send a message does not belong to the first mobility class and the encountered node met destination node of the message in the near past, then the message is transferred to encountered node.
Mobility class: the mobility management was divided into two categories: host-based and network-based.
Its 3′ conserved segment (3′-CS) contains 5 tns genes (tnsA, tnsB, tnsC, tnsD and tnsE) functioning in the movements of transposon [ 56], which mediates the mobility of class 2 integron via a preferential insertion into a unique site within bacterial chromosomes [ 30, 57].
After a predefined number of time slots, outdated parts are updated depending on the reported mobility class of the users.
Taking model OLS 1 for example, those who experienced upward mobility on average have 0.28 higher status discordance than those without perceived mobility, around one third of the class scheme.
In December 2011, the district court granted Apple and AT&T's motions to compel arbitration, following the Supreme Court decision in AT&T Mobility v. Concepcion, and decertified the class; in April 2012 the Ninth Circuit denied plaintiffs permission to appeal.
(2) If a node wishing to send a message not belongs to the first mobility class and encountered node belongs to the same or higher class than the source node mobility class then he transfer its message and assign this message half the number of replicas.
