station needs to collect connectivity information from nodes periodically An implication of this is an increased message overhead in collecting topology information 1843 Energy constraints Most nodes in ad hoc networks run on batteries Thus, we need to ensure that the network management overhead is kept to a minimum so that energy is conserved Different energy is consumed by a radio when a packet is transmitted or received In addition, the CPU expends energy in processing these packets Thus, we need to reduce the number of packets transmitted/received/processed at each node This requirement is contradictory to the need for topology update messages previously discussed 1844 Network partitioning Energy constraints and mobility can result in the network becoming partitioned frequently For instance, nodes may power themselves off to conserve energy resulting in partitions, or a node may move out of transmission range of other nodes.

Similarly, a node may die when its battery runs out of power In all these cases, the partitioned subnetworks need to continue running independently, and the management protocol must be robust enough to adapt For instance, when the network gets partitioned, the management protocol entities must quickly learn that the partition has occurred and recon gure the subnetwork(s) to function autonomously Furthermore, when partitions merge, the management protocol must be capable of updating the network view without too much of an overhead 1845 Variation of signal quality Signal quality can vary quite dramatically in wireless environments Thus, fading and jamming may result in a link going down periodically An effect of this is that the network topology from a graph theoretic point of view changes However, the physical layout of the network may not change at all.

each iteration Each expression within the for loop corresponds to a statement (It is easy to remember that the separation character between expressions is a semicolon and not a comma, because each expression is a statement) You write a for loop generically as follows: for(initial; boolean-expression; loop) statement

Here is a breakdown of the for loop The initial expression performs operations that precede the first iteration In Listing 342, it declares and initializes the variable count The initial expression does not have to be a declaration of a new variable It is possible, for example, to declare the variable beforehand and simply initialize it in the for loop Variables declared here, however, are bound within the scope of the for statement The boolean-expression portion of the for loop specifies an end condition The loop exits when this condition is false in a manner similar to the while loop's termination The for loop will repeat only as long as boolean-expression evaluates to true In the preceding example, the loop exits when count increments to 64 The loop expression executes after each iteration In the preceding example, count++ executes after the right shift of the mask (mask >>= 1), but before the Boolean expression is evaluated During the 64th iteration, count increments to 64, causing boolean-expression to be false and, therefore, terminating the loop Because each expression can be thought of as a separate statement, each expression in the for loop is separated by a semicolon The statement portion of the for loop is the code that executes while the conditional expression remains true If you wrote out each for loop execution step in pseudocode without using a for loop expression, it would look like this:

The management protocol must be able to distinguish this case from the case when node moves cause topology changes, because in the case of changing link quality/connectivity, it may not be necessary to exchange topology update messages at all In order to be able to do this, the management protocol entity (which resides at the application layer) must be able to query the physical layer This obviously violates the layering concept of OSI, but it results in enormous savings 1846 Eavesdropping Ad hoc networks are frequently set up in hostile environments (eg battlesite networks) and are therefore subject to eavesdropping, destruction and possibly penetration (ie a node is captured and used to snoop) Thus, the management protocol needs to incorporate encryption as well as sophisticated authentication procedures 184.
